Xorg.0.log with modeset enabled and output of dmesg while problem is active

When using nouveau with modeset, the system starts up fine but eventually
(possibly when the screen saver kicks in), X consumes all CPU resources on one
core rendering the machine useless except via ssh sessions. If I disable
modeset at boot time (nouveau.modeset=0), then the system is stable but the
drive does not accept the EDID from the monitor and I'm stuck with a 1024x768
display instead of the 1600x900 it has with modeset enabled.

I'm attaching the Xorg.0.log file along with an excerpt from the output of
dmesg when this behavior is occurring.

Hi Rick

Before jumping to compulsions can you configure your Xserver to not load
* libglamoregl.so
* vesa_drv.so
* modesetting_drv.so

The last two should be ignored if you use an xorg.conf as shown in here [1].
Whereas for the first one you could try an temporary rename the file (there may
be a better way to handle it, which I'm not aware of).

With that said, try and narrow down what's causing the issue. A scenario such
as
* as soon as my screensaver kicks in
* using program XX
* doing action A, while using program YY, followed by action C.

As the issue occurs, try and attach the complete output of dmesg (or save the
output to a file and attach at a later point)

Cheers
Emil

There is no xorg.conf file. This is a fresh, virgin install of Fedora
19, then updated.

I stated that it appears to occur when the screen saver starts and I did
include the dmesg data that started to spew out when the problem occurs.
That being said, I will restart everything and disable the screen saver
completely.

AFAICS I've asked you to try using an xorg.conf, rather than "Are you using one
how?" :P

You mentioned "possibly when the screen saver kicks in", which indicates a wild
guess :P With that confirmed which screen saver you're talking about -
bubble3d, etc.

There is a reason I've requested dmesg output, the one you attached is at
rather unknown point with absolutely no information as to how nouveau handles
your card :\. That's why I've mentioned a _complete_ dmesg. If you feel there
is something confidential inside if clearly strip it out

Now this is interesting

[19.600630]
Initially the kernel "drm" seems to pass NULL pointer to the card, while doing
nv50_fbcon_imageblit()

ch 1 [0x0007cb0000 DRM] subc 3 class 0x502d mthd 0x0860 data 0x00000000

The way I see it, after this point we're on the mercy of the hardware

[19.627513]
X/the ddx
MP is still funny and fails to execute/set EDGEFLAG_ENABLE to 1 (which for the
sake of me I cannot find in the ddx code?) 

[55.041877]
At this point the GPU is completely stuffed fails to execute/set
NV50_2D_BLIT_SRC_Y_INT, (coming from X).

After that hell breaks loose :P


Rick a few interesting notes
In the last attachment Xorg.log claims that it's starts at ~81.456, whereas
dmesg states that X was running ~19.627541.
* Are those logs matching (ie. captured from the same boot/system startup)
I'm assuming that you've started your screensaver ~55.041877. Is that correct ?
* Do you recall when did your nouveau started started reporting errors (nouveau
E) ?

Note: the following messages are harmless
nouveau E[    PBUS][0000:02:00.0] MMIO read of * FAULT at 0x1002**

Cheers
Emil

Emil, thanks for looking at this. It's, uhm, interesting, isn't it?

For clarity sake, this is a bit of an odd system. It's a Shuttle 
motherboard. From "dmidecode":

Handle 0x0002, DMI type 2, 8 bytes
Base Board Information
    Manufacturer: Shuttle Inc
    Product Name: FN78S
    Version: V10
    Serial Number:

I booted the machine and as soon as the display locked up, I ssh'd to it
from another machine and simply did a "dmesg >/rick/dmesg.txt" to
capture as much as I could. The Xorg.0.log was already generated by the
time I logged in via ssh. I combined the various logs into one file and
shot it off to bugzilla.

As far as the screen saver, I'm running XFCE and the lockup occurred as
soon as I went through the "Applications Menu->Settings->Screensaver"
menu tree. It tried to render the Screensaver window, got as far as
drawing the box around it and everything locked up. After about a
minute, the graphical screen blanked and I started getting the GPU
lockup and going back to fbcon messages appeared on the console. The
GUI screen then reappeared but it was still locked up. Again it
cleared, the GPU lockup message appeared again and around and around we
go. It might do the same thing rendering other windows, but I'm trying
to be consistent to help debug this.

I'll be more than happy to keep tinkering, but I've had like 3 hours
of sleep in the last two days and I'm a bit knackered. I can pick this
back up Monday. I'm in California if that's of any help.

Glad to hear that! That's the first thing that appears after the
plymouth "fill the bubble" screen and before I get the GDM login.

I'm talking about nouveau errors in general, indicated by "nouveau E"
disregarding the I've mentioned as harmless. If unsure attach dmesg of older
kernels that you have handy :)

Also you can try this simple patch, it would trigger a kernel bug so be warned.
If/when it does capture the output and attach it in here (either in picture or

In answer to your first question (I think), yes, those captures were from the
same boot/crash cycle, acquired as I mentioned in my comments.

In answer to the second, I'm not sure how to correlate the timestamps. Looking
at the dmesg output, the first "nouveau E" message occurred 19 seconds into the
boot process. This is long before the login screen for the desktop appears.

The next messages seem to occur once I log in via the desktop login screen,
about 55 seconds after the boot. The screensaver shouldn't start for at least
10 minutes after that. As I said, if I try to do something such as adjust the
screen saver parameters via XFCE's "Applications Menu->Settings->Screensaver"
menu, as soon as the frame containing the the applications window is rendered
the display, keyboard and mouse lock up.

dmesg is wiped each time I boot the machine. I guess I could try to set up
something that would log it to a disk file instead of just in the ring buffer.

I'll need to free up some time this week to build a new kernel. I'll put it on
the "got to do" list.

Obviously I did not express myself clear enough :)

The Xorg.0.log attached is _not_ from when the crash/lockup occurred. It is
from the second X session (the one that was started by your system after X died
the first time). I was seeking confirmation of the above with my first question
:P

Does your system has plymouth or similar splash manager ? Please disable it,
try to reproduce the issue and attach dmesg _before_ trying the
patch/recompiling the kernel

Please do not assume that I'm running XFCE and/or know what exactly it does
behind the scenes. The name and/or package of the screensaver would be great :)

No need for such an overkill

All I was asking - "Is this a kernel regression ?", or in other words
"before you installed Fedora 19 with kernel 3.9.9, you had XXX, running kernel
XXX. Do you recall any messages similar to 'nouveau E' in dmesg?"

Quick $grep "nouveau E" -r /var/logs/ may help depending on your setup

Cheers
Emil

Sorry, forgot to comment about the attachment I just put up.

The machine did use plymouth, so I removed the "rhgb" stuff from the boot
command and repeated everything as before, but included both Xorg.0.log[.old]
files and another capture of dmesg.

The screensaver is "xscreensaver" and the menu tree fires up
"xscreensaver-demo".
They come from the xscreensaver-5.22.1.fc19.x86_64 set of RPMs. The system is
up-to-date running kernel 3.10.3-300.fc19.x86_64.

Oh, one additional thing...nouveau never seemed to work with this hardware.
Before I upgraded this machine to F19, it had been running F18 but I ended up
running the nvidia blob driver system since I never could get nouveau to work.
I could go back to that if needed, but I thought that since this is currently
an experimental system, I might try to get nouveau to work properly and
possibly help the community.

I do appreciate your help on this Emil. I just wanted you to know that and if I
seem a bit, well, dense it's because I'm not that familiar with how the entire
X mechanism works on this sort of hardware.

We all have our strengths and weaknesses :)

Looking at your latest dmesg, the pointer have changed from 0 to another
(probably invalid) value - 0xfe00ccc6

nouveau E[  PGRAPH][0000:02:00.0] ch 1 [0x0007cb0000 DRM] subc 3 class 0x502d
mthd 0x0860 data 0xfe00ccc6

Would be great if you can do the following

* Notice if the the value varies between reboots, or does it differ on kernel
version

example
       kernel version
       3.9.9   3.10.5
boot
1      0xbla0  0xbla1
2      0xbla2  0xbla3
3      0xbla4  0xbla5

Rick there is no need to try the BUG_ON(!data).patch

I was assuming that the data printed by nouveau indicates the CPU
pointer(rather than one from the gpu's vm), silly me.

That said, the only thing that I can think of is that either the VM is not
setup properly or data is getting overwritten somewhere :\

Either case a mmiotrace of the blob may be great to have [1], although not too
sure when I'll have some time to look into it

Cheers
Emil

mmio trace along with dmesg and Xorg logs

I did as you asked...rebooted in run level 3 with plymouth disabled. Started
the mmio trace, then started X by using "telinit 5", tried to bring up the
screen saver stuff, waited for it to lock up, waited until it restarted, then
stopped the mmio trace and grabbed dmesg and the last two Xorg log files.

I hope that gives you more insight. I await your feedback.

Did you mmiotrace nouveau or the nvidia proprietary driver? The request was for
the latter. [Although I don't really see how that will help... but I also
haven't looked at all the details of this bug.]

It would be worth testing 3.11-rc7 on this (or 3.11 if it's out by the time you
get to it).

I wonder if there's a bug somewhere handling the NVAA as NVA3+ (which it's
not). But then NVAC would also be affected... or something in the ctxprogs...
(I guess for which the mmiotrace could come in handy.)

The fact that he had F19 when he opened the bug report doesn't imply that he
didn't upgrade to F20 or F21 since his last post.
Besides, one can compile a kernel, or test using one of the live images here:
