Description capsel 2010-03-12 17:24:28 UTC
Screens goes black (or almost black... grey?), somtimes I could see some random color bars across screen. I'm not certain about conditions as it happened after several hibernations and suspends, after about 2 hours of normal work.

After a blank-out I can switch from X (alt+ctrl+f1) and press alt+ctrl+delete to restart, but screen is still blank. Pressing alt+ctrl+f7 (to X) does not help.

The only error is in /var/log/messages:
kernel: [drm:i915_gem_madvise_ioctl] *ERROR* Attempted i915_gem_madvise_ioctl() on a pinned object

I wanted to try new kernel on msi wind u100 as 2.6.32 series gave almost instant blank-outs (black, pink...).

I'm using gentoo, and it's kernel 2.6.31-gentoo-r10, and it works fine.

2.6.34-rc1 works fine with the KMS driver on my Wind U100.  Can you try this one, please?
Comment 2 capsel 2010-03-15 23:18:44 UTC
I did not hibernate or suspend and screen didn't have any unusual colors but...
After 2 hours since boot screen froze. Everything was still but mouse cursor, which changed it appearance (arrow, text, resizing) according to what was on screen. So I killed X.

from syslog:
kernel: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
kernel: render error detected, EIR: 0x00000000
kernel: [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 980788 at 980776)

and that was 2.6.34-rc1
Comment 3 capsel 2010-03-15 23:30:54 UTC
I forgot to mention that I could switch from text console (with KMS) to X and back. Screen in X was frozen - nothing changed - but console was working.

And 1 hour not 2.

...that's kind of progress, isn't it?
Comment 4 Rafael J. Wysocki 2010-03-21 19:35:01 UTC
What version of the user space Intel driver do you use?
Comment 5 capsel 2010-03-22 00:07:37 UTC
from emerge -s intel:

*  x11-drivers/xf86-video-intel

any other info I can give to help?

Just few seconds ago, under 2.6.34-rc2, screen started flickering. I'm running kde-4.4.1, on one (virtual) desktop rsync, on other www browser. There are no messages in dmesg or Xorg.0.log about this. After switching desktops for a while the effect disappeard.
Comment 7 capsel 2010-04-04 13:57:39 UTC works somewhat better. Sometimes screen becomes black for a moment (less than second) or mouse cursor looks like few bitmap lines switched their places. But now under xfce/compiz.
Comment 8 capsel 2010-04-09 09:45:52 UTC
This bug is still valid. What info should I give?

Comment 10 capsel 2010-04-11 13:38:04 UTC
To be more precise - every 2.6.32.(-10) and 2.6.33.* and 2.6.34-rc{123} does not work well. This is a regression but from 2.6.31 series.

Some time ago gentoo unmasked 2.6.32 series kernel, but it does not work - same symptoms, even without hibernation/suspend.

How can I help, can someone direct me?
Comment 11 capsel 2010-04-20 10:28:49 UTC
I'm testing gentoo-sources-2.6.33-r1, which seems to include patches, and user space driver 2.11.0 for over a week, and all seems to work well.
Comment 12 capsel 2010-04-21 18:41:06 UTC
...and screen went black. kernel ("vanilla"), driver 2.11.0. No messages in /var/log/messages od /var/log/Xorg.0.log.
Comment 13 capsel 2010-05-26 10:27:29 UTC
Now I'm using kernel 2.6.34 and driver 2.11.0 since it (kernel) was released and it works well
Comment 14 Chris Wilson 2010-07-24 09:26:35 UTC
Yes, you hit both a userspace bug which was attempting to re-use pinned (since they were being used for scanout) buffers. As noted, fixed in xf86-video-intel-2.11.0
