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?
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
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?
What version of the user space Intel driver do you use?
from emerge -s intel: * x11-drivers/xf86-video-intel Latest version available: 2.9.1 Latest version installed: 2.9.1 Size of files: 770 kB Homepage: http://xorg.freedesktop.org/ Description: X.Org driver for Intel cards License: MIT 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.
2.6.33.2 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.
This bug is still valid. What info should I give?

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?
I'm testing gentoo-sources-2.6.33-r1, which seems to include 2.6.33.2 patches, and user space driver 2.11.0 for over a week, and all seems to work well.
...and screen went black. kernel 2.6.33.2 ("vanilla"), driver 2.11.0. No messages in /var/log/messages od /var/log/Xorg.0.log.
Now I'm using kernel 2.6.34 and driver 2.11.0 since it (kernel) was released and it works well
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
