Is there any chance that you could connect a serial line to the machine? 
Your report about blinking keyboard led's means that there's an oops, but 
since the display isn't in textmode (and the oops obviously happens when 
trying to enter it), we don't know what it is.

A serial line (along with a kernel compiled with serial console support, 
of course, and a kernel command line option like "console=ttyS0,115400 
console=tty0") would get that. You'd just need another machine with a 
terminal program like minicom..

The network console could also work out, but serial lines tend to be more 
reliable if you have them. But in the absense of serial lines, see the
Documentation/networking/netconsole.txt file for some details. The setup 
is more complicated, but on the other hand it's a lot more dynamic, and in 
your case - since the box works until you try to switch to text-mode, I 
suspect the network console dynamic run-time setup would be easy for you 
to use.

(For other examples of using netconsole with that dynamic mode, just 
google for "sys/kernel/config/netconsole" and you'll find a number of docs 
that explain how to find the MAC address for setup etc).

The system does not have a serial console, but I was able to set up
netconsole. For what it is worth, I did not do this until now because
(1) I was able to bisect the problem, and (2) I asked driver developers
directly how I can help to debug this and I received no response.

As you can see from the kernel version it is not a build of a vanilla
kernel. It only contains changes related to the wireless networking work
I am doing.

Here is the output:

Thanks, this is great. It pinpoints the problem very effectively.

The code here is

	  16:	48 8b 80 00 01 00 00 	mov    0x100(%rax),%rax
	  1d:	48 8b 50 08          	mov    0x8(%rax),%rdx
	  21:	48 85 d2             	test   %rdx,%rdx
	  24:	74 11                	je     0x37
	  26:	49 8b 44 24 78       	mov    0x78(%r12),%rax
	  2b:*	8b 80 84 00 00 00    	mov    0x84(%rax),%eax     <-- trapping instruction
	  31:	89 82 08 08 00 00    	mov    %eax,0x808(%rdx)
	  37:	f6 45 a0 02          	testb  $0x2,-0x60(%rbp)

and that "testb $0x2, -0x60(%rbp)" seems to be the

	if (iir & I915_USER_INTERRUPT) {

test if I'm reading things right. Although it could also be the

	if (eir & I915_ERROR_MEMORY_REFRESH) {

thing. The disassembly is totally impossible to read, because the stupid 
i915 driver is chock-full of crap like

	if (IS_G4X(dev)) {
		..

which expands to insane amounts of code that check the PCI ID's one by 
one.

Intel guys: could you _please_ stop doing that. Create a capability mask 
in the device or something, so that you can test for "is this a G4x" with 
a single bit test, rather than have code like this:

        mov    0x31c(%rsi),%eax
        cmp    $0x2982,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x2972,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x2992,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x29a2,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x2a02,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x2a12,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>

        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x2e12,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x2e22,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x2e32,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>
        cmp    $0x42,%eax
        je     0xffffffff8124b669 <i915_driver_irq_handler+177>

for that IS_G4X() thing (I'm not kidding - that's exactly a hundred bytes 
of code for that _stupid_ test, and it's inlined!)

Anyway, we're getting that DRM irq, and it has a normal IRQ stack trace:

.. but it happened just as we're tearing down the DRM irq handling:

so what is going on is that the i915 driver has obviously torn down some 
state before it uninstalls the irq, so the irq happens when the state has 
already been torn down, and the irq handler is not ready for that.

This patch *may* fix it - simply by getting rid of the irq early. However, 
I did not check whether maybe something in i915_gem_idle() actually needs 
the interrupt to be able to happen, so this is TOTALLY UNTESTED!

Yeah things are getting a bit out of hand there...  We've moved to
feature tests for some things, but they're still PCI ID based; however
they should be easy to convert.

Theoretically i915_gem_idle should prevent any user interrupts from
coming in.  If we uninstall the IRQ first we i915_gem_idle probably
won't work anymore, since it queues an interrupt and waits for it.

Eric, any thoughts on this?  We shouldn't be racing to queue new work
after the idle call since we suspend GEM at that point, so we must be
failing to manage our active lists properly somehow?

That is _entirely_ immaterial.

The thing is, interrupts can be shared. So it does not matter ONE WHIT 
that you are trying to idle the hardware - there may be _other_ hardware 
in the machine that is not idle, and that raises the same shared 
interrupt. End result: the irq handler will be called, whether your 
particular hardware is idle or not.

So if you tear down data structures that the interrupt handler needs, you 
_ABSOLUTELY_ must first unregister the whole interrupt.

Also, even if there are no shared interrupts or any other devices, there 
can easily be old pending interrupts still queued up on IO-APIC's etc. So 
even though you quiesce the hardware, there is no guarantee that there 
aren't some pending interrupts that happened just before you turned off 
the interrupt from the hardware side, and are still "en route" to the CPU.

Which gets us exactly the same rule as if there were shared interrupts: if 
your interrupt handler depends on some data structure, you must tear down 
the interrupt handler _before_ you tear down the data structures it 
depends on (and in the reverse order when setting things up, of course).

So then you'd better fix that. Because the code as is is very 
fundamentally buggy.

See my previous email. The bug is that you do

  i915_gem_cleanup_ringbuffer ->
    i915_gem_cleanup_hws ->
      dev_priv->hw_status_page = NULL;

while interrupts are still enabled and coming in. And the interrupt path 
wants to access that hw_status_page. Which you just destroyed.

Which is fine.  We can handle interrupts in the shared case.  It's
specific IRQ statuses we can't handle.  E.g. if we've explicitly turned
off vblank events we definitely won't expect to see them in the handler
(assuming we've taken care to barrier things like you mention below).

The way we barrier things should handle that case.

Yeah, saw that.  I don't think that's the root cause though.  If we see
a user interrupt after gem_idle is called we may have serious issues in
our command handling code.

Quite frankly, I do not understand why you seem to be making excuses for 
code that causes a very nasty and undebuggable oops, causing the machine 
to die. 

This regression is almost two months old, and apparently the Intel 
graphics people DID ABSOLUTELY NOTHING about it during those two months, 
because they couldn't be bothered to look at it.

And now, when I pinpointed exactly where the oops happens, and what the 
cause is, you seem to be trying to hold things up. I wanted to do the 
final 2.6.31 release yesterday, quite frankly I'm not in the _least_ 
interested in excuses, I'm interested in something that at least gets us 
back to the 2.6.30 state that doesn't oops!

Get me a patch, please. If disabling the interrupts early won't work, get 
me something else. Stop delaying it - it's been pending for 48 days 
already.

No excuses.  This is a serious bug; I just don't want to paper over it.

Yeah sorry, this is the first I've seen of it...  I usually troll the
regressions lists but I must have missed this one.

Hmm. We must have screwed up something, because this was bisected to the 
intel DRI commits back in July. See

	http://bugzilla.kernel.org/show_bug.cgi?id=13819#c4

and while there was some confusion about exactly which commit caused 
it - probably because the irq thing obviously depends on timing - 
Reinette had a list of three commits that he used to be able to revert to 
get things going:

   drm/i915: Don't update display FIFO watermark on IGDNG
   drm/i915: add FIFO watermark support
   drm/i915: enable error detection & state collection

So Andrew assigned it to DRI, and Rafael has had both Eric and Ma Ling on 
the cc for his regression reports because of the bisection. And that has 
been going on for a long time, I just checked:

    Date: Sun, 26 Jul 2009 22:28:26 +0200 (CEST)

    Subject: [Bug #13819] system freeze when switching to console

If you didn't see it, then that means that we have screw-ups with the 
bugzilla thing. You're actually listed as a "Reviewed-by" on the commit 
that the fixed-up bisection blamed - And I get the feeling that Rafael's 
bugzilla "bugme" scripts may only pick up "Signed-off-by:" lines.

The point is: this bug has been in bisected in bugzilla for a month and a 
half, and had at least two Intel DRI people cc'd on the weekly reminder 
reports, along with being

	Assigned To:  	drivers_video-dri-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org

We have other bugs on the regression list that are even older (no, I'm not 
proud of them):

	http://bugzilla.kernel.org/show_bug.cgi?id=13809
	http://bugzilla.kernel.org/show_bug.cgi?id=13740
	http://bugzilla.kernel.org/show_bug.cgi?id=13733
	http://bugzilla.kernel.org/show_bug.cgi?id=13645

but they aren't bisected and it's not nearly as clear what is going on 
there. The last one in particular I don't know if it even happens any 
more and the first one seems to be fixed in -rc5, or at least the 
reporter couldn't reproduce it any more..

Reinette actually mailed me offlist about this; we corresponded
privately about this issue a month ago; I lost track of it while on
vacation (yeah I'm not on the cc lists for the bz or regression
updates).  Totally my fault.

Anyway the bisects look like they might just be lucky; it sounds like
this wasn't a KMS related issue at all...

This one looks gfx related, upstream bug is
https://bugs.freedesktop.org/show_bug.cgi?id=23096.

The graphics group tracks freedesktop.org bugs on a weekly basis since
that's where a vast majority of our bugs our filed (often from OSVs);
I'll get the kernel bugzilla stuff included in our future scrubs so we
don't miss stuff like this.

Based on the earlier mail I thought this might have been a bigger
problem with the way we handle command submission and completion; but
on looking at things again (both Linus's debugging and your
configuration), I think this is actually a DRI1 & userspace related
issue.  Back in the DRI1 days, the X server told the driver when to
register and unregister its irq handler, and had some responsibility
for making sure it didn't hose things (very easy to do with the old
architecture).  Stuff like this was one of the main reasons we moved
most of the handling of this into the kernel...

We obviously need a kernel fix though; panics like this aren't
acceptable.

This fix is along the lines of Linus's initial suggestion; we
definitely are tearing down some state that the interrupt handler
needs.  And the 2D driver isn't saving us from ourselves like it used
to (previously it would uninstall the IRQ handler before tearing down
the mappings; but with the kernel in charge of those now, we have to
handle it).

This one should disable i915 interrupts (we'll still handle shared ones
just fine as no-ops) at the point where we no longer need them, then
let the DRM core code take care of finally unregistering it.

Ugly, but I'd like to know if it works for you.  Any chance you could
give it a try Reinette?

Yeah, that seems to be the right thing.

So the actual faulting instruction is from this:

                if (dev->primary->master) {
                        master_priv = dev->primary->master->driver_priv;
                        if (master_priv->sarea_priv)
                                master_priv->sarea_priv->last_dispatch =
					READ_BREADCRUMB(dev_priv);

and it looks like %rax starts out being 'dev', then the

	mov    0x100(%rax),%rax

means that %rax is now 'dev->primary', and then

	mov    0x8(%rax),%rdx

moves 'dev->primary->master' into %rdx. It's not zero, so we then do that 
READ_BREADCRUMB(dev_priv), which expands to

	READ_HWSP(dev_priv, I915_BREADCRUMB_INDEX)

which in turn is

	(((volatile u32*)(dev_priv->hw_status_page))[reg])

and it looks like dev_priv->hw_status_page is NULL.

You can verify this by looking at teh exception address:

	BUG: unable to handle kernel NULL pointer dereference at 0000000000000084

and that '84' is I915_BREADCRUMB_INDEX*4 (0x21*4).

And the problem seems to be that we've cleared the hw_status_page pointer 
in i915_gem_cleanup_hws():

	dev_priv->hw_status_page = NULL;

and we did that in 

  i915_gem_idle() ->
    i915_gem_cleanup_ringbuffer() ->
      i915_gem_cleanup_hws()

so now since interrupts are still enabled, you'll get a NULL pointer 
dereference.

I think my patch is correct.

Do you see "hardware wedged" messages in your log after using Linus's
patch?  That's what I'd expect...  ah no I see we don't call the
routine that requires interrupts in that path like I thought.

So Linus's patch is fine with me.

I can confirm that. While using this patch, when I am in X and then
switch to console and back to X there are no new messages (checked with
dmesg).

So simply switching VTs causes this problem too?  Based on your initial
description it sounds like a panic (keyboard LEDs were flashing).  If
it happens at VT switch time you should be able to capture the panic
output with netconsole like Linus mentioned.

I had the same problem here at least since -rc4. Oliver already did a two-liner
patch to fix the issue. Can be found here:

http://bugzilla.kernel.org/attachment.cgi?id=23046

It fixes the issue for me on two different cdc_acm devices. Don't know if it is
already in the USB tre, but I had to apply it to linus HEAD from today. Would
be good to get this in before the -final as it would cause a real regression.

Good question: I don't think so.  It's not in mainline as of 2.6.31.
Looks like we need to keep this bug open a while longer...  Sorry 'bout

AFAIK, this is still a problem. Have requested more information in

As an aside, the subject seems to have lost the iwlagn aspect of this

2.6.32-rc4: Reported regressions 2.6.30 -> 2.6.31

[Rafael J. Wysocki]

[Note:
  10 new reports in the last 10 days, but fortunately we're fixing them faster
  than they're being reported.]

This message contains a list of some regressions introduced between 2.6.30 and
2.6.31, for which there are no fixes in the mainline I know of.  If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.30
and 2.6.31, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

Actually I switched to -32rc so I can't test it anymore... Sorry. I
can confirm it for 2.6.31.1.

Please have a look at my other bug report which applies to 32rc (#14372).
The result is the same (wifi down after resume) but the warning does
not show up.

The "cure" is also the same (rfkill-off followed by rfkill-on).

   highest ever.]

This message contains a list of some regressions introduced between 2.6.30 and
2.6.31, for which there are no fixes in the mainline I know of.  If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.30
and 2.6.31, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Hi.
I suppose this is still valid. I had to work around it by rfkill-ing
the device during the suspend process and reenabling at resume time.

I can try to reproduce it with 2.6.31.1 if you want it.

In fact I'm more interested in whether or not it's still present in the Linus'
tree.

Well, I just tried 2.6.32-rc1-git3 and I have to say that it's mostly
useless with my eeepc. The warning didn't show up after resume but it
was impossible to reassociate with my AP and after some tentative the
screen went blank.

I was able to poweroff the netbook using the power button but I'm a
little scared to try again.

Maybe I'll try with -rc3 or something.

It shouldn't kill the system cold dead, so as long as you have your data
backed up, you can do some debugging IMHO.

> Maybe I'll try with -rc3 or something.

I guess you should report the issues you have at the moment.  Then, it's
actually more likely that someone will take care of fixing them.

OK. This is what I've been able to come up with so far:

* with 2.6.31.x the warning shows up more or less every suspend-to-ram cycle;
* with 2.6.32-rc the warning never shows up;
* with 2.6.31.x when the warning shows up wifi is unusable until rfkill cycle;
* whith 2.6.32-rc after suspend-to-ram cycle wifi is unusable and
rfkill does not cure it unless I rfkill it off - suspend-to-ram -
resume - rfkill it on. This seems to work.

When wifi does not work in 2.6.32-rc the messages show:

---------------------------------------------
[   49.647233] wlan0: direct probe to AP xx:xx:xx:xx:xx:xx (try 1)
[   49.649234] wlan0: direct probe responded
[   49.649244] wlan0: authenticate with AP xx:xx:xx:xx:xx:xx (try 1)
[   49.650546] wlan0: authenticated
[   49.650581] wlan0: associate with AP xx:xx:xx:xx:xx:xx (try 1)
[   49.652183] wlan0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x451
status=12 aid=1)
[   49.652190] wlan0: AP denied association (code=12)
---------------------------------------------

The script I feed to pm-utils to have wifi work across the
suspend-to-ram cycle is just:

---------------------------------------------
#!/bin/sh
RFKILL=`basename /sys/devices/platform/eeepc/rfkill/*`

case "$1" in
	hibernate|suspend)
		cat /sys/devices/platform/eeepc/rfkill/$RFKILL/state > /tmp/suspend
		echo 0 > /sys/devices/platform/eeepc/rfkill/$RFKILL/state
		;;
	thaw|resume)
		cat /tmp/suspend > /sys/devices/platform/eeepc/rfkill/$RFKILL/state
		;;
	*) exit $NA
		;;
esac
---------------------------------------------

I can confirm that with 32-rc sometimes the screen flickers badly
after resume, for example running a simple dmesg command. However,
nothing is written in the logs, neither messages nor Xorg.0.log.
Chipset is i915.

Hope this helps. Please note that git is not an option for me on this machine.
