It happens 2-3 times in hour and it's not related to Firefox - the same crash happened when I browsed a document in evince.

Xorg.log after crash
Is there any extra info I can provide? I didn't see the bug before I moved my production box to RHEL6, everything works fine on Fedora 12.
*** Bug 592434 has been marked as a duplicate of this bug. ***
I'm having the same problems as descripted in https://bugzilla.redhat.com/show_bug.cgi?id=592434. But I'm able to switch to the console using ctrl+alt+f#.
still a problem original reporter?

crash log from today
Yes, I can still reproduce it although not every day.
When this happens, please do:
# mount -t debugfs debugfs /sys/kernel/debug
# cat /sys/kernel/debug/dri/0/i915/i915_error_state > /tmp/i915_error_state
and attach the resulting error state file to this bug.
I'm unable to reproduce this any more (Thinkpad T400 / x86_64)
Lubos, what kernel are you running now?
Removing from blocker list for comment #12. Martin, please re-set blocker? if you are still seeing this.
I haven't reproduced it since the last crash I posted here. Will update the bug when it happens again.
I'm not able to reproduce this on my desktop with:
But Xorg behaves similar during RHEL6.0 installation. May this be somehow connected to #603003?
Can anybody who suffered from this try to reproduce #603003 (Switch from Xorg to Console and back (during latest RHEL 6.0 installation)?
This and bug #603003 are almost certainly not the same issue. Even if they are, let's treat them separately instead of confusing them.
Comment #15 and comment #16 sound like _this_ issue is resolved. 603003 might not be, but let's follow up on that there.

state log 2
X crashed again, second log. It usually happens when I'm scrolling a page in Firefox or pdf reader (evince).
Well at least those two error state files are consistent. They both decode to something like:

The HEAD pointer is consistently stalled at the INDEPENDENT_ALPHA_BLEND op. I'm guessing that there's some hardware errata that means you can't change that bit of 3D state while some 3D processing is active.
Martin, can you try this build and report
a) whether it's noticeably slower
b) whether you can still reproduce the lockups
Okay, I'll try it tomorrow. But the graphics looks pretty slow already, in some moments (repainting whole screen for example) looks like a VESA driver instead of accelerated one. It's definitely worse user experience than I have with Fedora 12.
With the packages from http://download.devel.redhat.com/brewroot/scratch/ajackson/task_2597465/ X window does not start. It keeps flashing and turning monitor on and off.

does the build from here help any? it might be a bit chatty in the logs.
I reinstalled my box completelly and with xorg-x11-drv-intel-2.11.0-6.el6.i686 and no crashes so far. Will check your new package.
With packages from https://brewweb.devel.redhat.com/taskinfo?taskID=2606300 it freezes after login do gdm. All logs (X, X.old, messages) are clear...
btw. I can reproduce the same bug on rawhide (on the same box).
when finished will end up at
can you guys install that kernel on a clean EL6 and see does it enhance your experience?
closing this as a duplicate of the other 945GM bug which has flags.
