I'm confirming the problem still exists with Maverick x64 kernel 2.6.35-22 running KDE4. System is Thinkpad T400 using Intel 4500. Sometimes a hard reset is the only way, sometimes I was able to switch to a VT and get those message around (but not exactly) every second (based on the timestamps):
[4200.123456] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [4200.789012] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 264334 at 263373) The number "263373" stays constant, while the number before it ("264334") increments by 2 everytime a message is printed. Most of the time this happen when some desktop effect is used. I also noticed that most of the time the effect was "Present Windows", which is also buggy (i.e. window thumbnails disappear after around a second) -- [i855] GPU hung (drm i915 intel) on Lucid Lynx https://bugs.launchpad.net/bugs/528467 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
