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

kernel version 3.5.2 (yes, I'll try to upgrade). Sometimes also the X-server freezes and restarts with no errors in dmesg. Is it a known problem?
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.
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!
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
