Hi all
Sorry, not sure what information is most appropriate here. GPU hangs from time to time on this laptop, typically when running firefox on graphics-intensive sites. Error log at the bottom. Distro is Debian 6.0.6 (squeeze), lspci

I have the same problem, are able to reproduce it and have bisected it, but the commit which git --bisect identified seems not to be the cause.

This is a quite nasty (3.7) regression. I have it on all of my three machines and it drives me mad (3.6.x hangs my USB 3.0 port and 3.7 my intel graphics).
Try to boot with "i915.i915_enable_rc6=0" and switch to SNA in your Xorg.conf:
Section "Device" Identifier "Card0" Driver "intel" Option "AccelMethod" "SNA" EndSection
There are tons of this "GPU hangcheck timer elapsed" messages on the net...
Good luck!

Note that Guennadi is running kernel 3.5 which does not contain that patch - generally there are billions of ways to hang your gpu, so every gpu hang needs it's own bug (until we've analyzed the error_state and triaged the bug taking other evidence into account). Also, this is on a different gpu generation, so even more likely that it's a different kind of hang.
Thanks, Daniel

Upgrading to 3.7 highly recommended, if just to get the recent pile of gpu reset fixes - those should increase the chances that the reset works and your system survives. Also worth testing is upgrading userspace gfx driver components to the latest versions (mesa + xf86-video-intel). If you still have gpu hangs with all that, please file a bug report against DRM -> DRI/Intel and please attach the i915_error_state from debugfs after your gpu hung).
Yours, Daniel
Hi Daniel
Sorry for a late reply.

Did that and it did work for a while, longer than the average with 3.5. I was already about to write a success report, but then it hung again yesterday. I'm not using this laptop very intensively, so, it is hard to collect statistics.
Also worth testing is upgrading userspace gfx driver components to the latest versions (mesa + xf86-video-intel).
Not sure I'll be bothered - recompiling user-space is too much of a hastle ;-) Maybe I'll just upgrade my distro altogether. Thanks for the tips anyway!

You could try to reproduce the error by writing a big file e.g.
dd if=/dev/zero of=deleteme bs=1M count=80000
or similar and watching high definition video on Youtube (1080p) or running a few instances of glxgears. That triggers a gpu hang in my case after just a couple of seconds.
In my case, the hang doesn't occur when using SNA (or a kernel < 3.7, which isn't the case with your bug). I have this in my xorg.conf:
Section "Device" Identifier "Card0" Driver "intel" Option "AccelMethod" "SNA" EndSection
Without this, every 3.7 kernel produces a gpu hang within max. 1 min.
