With 2.6.36-rc5 and later my netbook is unusable. After login on X (KDE) the
screen gets totally garbled, under X and console too. The log shows me this

drm/i915: Fix Sandybridge fence registers
With 5 places to update when adding handling for fence registers, it is
easy to overlook one or two. Correct that oversight, but fence
management should be improved before a new set of registers is added.

The errors always happend with an external display connected. I've booted the

drm/i915: Fix 945GM regression in e259befd
A minor typo caused a single fence register to be incorrectly

I've the same kind trouble with -rc6 and my dell e6410. When module i915 is
loaded screen become black and i loose the hand on the system.
I don't have log message probably because my i915 is loaded in initrd and
kernel should crash before it's write something.
If you need more investigation, i can provide it.

Nope, completely different bug. eDP being the issue here. Though I think
the Dell 6410 is one of the few that Jesse has been able to get working
(in drm-intel--next)

You speek about eDP, but i don't use the external DisplayPort. Despite
that you think, this can be linked?
I have to add, that with 2.6.33 to 2.6.35.7 host start and drm/intel
works well ! I was so happy :)
If you need i report something i can do it, but at the moment,
starting with 2.6.36-rc6 produce no usable output for debug or
understanding what goes wrong.

eDP is embedded DP link to your laptop panel, it's an alternative replacement
for LVDS.

yeah, that time I did borrow one e6410 and it's working. Then it left
me and I got regression report on eDP from PCH DP port.

I sent mail before to ask if ajax's eDP connector type change for PCH/eDP
has caused regression for that, but one e6410 owner replied no effect by
revert that patch. You may help by bisect drm/i915.

Ok i can try (first time). To understand correclty what you want, i
have to download linux 2.6.36-rc6 git, bisect, compile an run kernel
until i found the commit cause the issue?
I will test new rc7 in near time to show if my display come back.

drm/i915: Ensure that while(INREG()) are bounded (v2)
Add a new macro, wait_for, to simplify the act of waiting on a register
to change state. wait_for() takes three arguments, the condition to
inspect on every loop, the maximum amount of time to wait and whether to
yield the cpu for a length of time after each check.
v2: Upgrade failure messages to DRM_ERROR on the suggestion of
Eric Anholt. We do not expect to hit these conditions as they reflect
programming errors, so if we do we want to be notified.

You are right, screen is just stay black. I can reboot my computer by
Ctrl-Alt-Del. But something is weird, after a led blink screen stay
black and need a power button push to stop computer (and an another to
restart it with a functionnal bios screen)

I've tried linux-next git patches and with this, display goes back to
normal and it's seems that compositing under kde 4.5 is now a little
bit fluent.
This is sad you cannot push fix in 2.6.36 because e6410 dell laptop
become completly unusable. Life is harsh.
I've one more question about i915. Do you know that i915 module and
recent version of Xorg have bad performance in a kde 4.5 compositing
environment? Do you think this is linked with eDP issues ?

Hello Chris,
i've tryed last git kernel with edp-fixes from
git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/drm-intel.git,
i've the following result :
http://videobin.org/+2a3/2kn.ogg
with intel-drm-next from
git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel.git,
it's better!
My screen is back. Do you include those patch in 2.6.37?
But:
- suspend to RAM cause a computer freeze.
- after one day, applications become graphically slow.
Regards,

For future reference.. its probably not a good idea to let that
condition persist. There is a chance it might damage the LCD if it is
powered but not being driven properly.

No clue there I'm afraid.

yes i've it, i merged linux upstream with drm-intel-next two hours ago.
I make an another video, which show suspend to ram issue with this
lastest kernel and how it's perfectly functionnal with 2.6.35.7.
http://videobin.org/+2a5/2kp.ogg
can i do something more to help your troubleshoot this issue?

If you have a working kernel version and a non working version (and some
time on your hands!), you could "git bisect" between the various
revisions to determine which commit introduced the breakage.
(NB: I'm not a driver developer here, just a keen user).
It took me a good long time bisecting a graphics regression when I had
it down to 80 changes. Since in that case I was sure it was a graphics
related fault - and had an idea which of the many driver source files
would be relevant, I was able to pass some extra parameters to git
bisect to narrow the search.
Others might disagree, but from your video I wouldn't be 100% sure that
I could restrict the search to the graphics driver only.

Yeah. i already done that. Issue comme from a comiit between
2.6.36-rc1 and 2.6.36-rc2.
I found the following commit : 913d8d110078788c14812dce8bb62c37946821d2
But Chris answer was a bit disappointing for me and i'm not sure that
help someone to fix issue on e6410 laptops.

Yes, -next is intended to be the basis of what is upstreamed for 2.6.37.

Depending on where the tip was, at least one suspend regression was
recently fixed. It would be useful to recheck with 64193406.

You're not alone. Eric has reported that writes to a GTT mapping become
glacially slow after some time, without any distortion in the CPU profile.
Can we collate what hardware we are seeing this effect on?

Yes i have this patch in, and the issue is still here.
Do you have seen this vmideo, which show the suspend to ram issue with
ailine and drm-next and how it's functional with 2.6.35.7?

Oh 6410. Yeah, that regression was pre-g4x. Do you have a good idea of the
precise range in which the regression was introduced, or is just another
eDP misery?

Just the chipset [Arrandale, in this case] for the time being, so I know
which machines to leave running to see if I can observe the effect here.

Would a dramatic slowdown in flash video framerates be a symptom of
this? If so, I'm also experiencing this after 1-2 days on an Arrandale.

This seems to be fixed in 2.6.37-rc1 and lastest git tree. :)
