Message-ID: <20110203221108.281c8512@duality> Date: Thu, 3 Feb 2011 22:11:08 -0600 From: Bobby Bingham <uhmmmm@...il.com> To: linux-kernel@...r.kernel.org Subject: drm:i915_hangcheck_elapsed Hi all, On my Sandybridge desktop, I occasionally had an issue under 2.6.37 where I would get something like this in my dmesg output and the X display would stop updating, except that the mouse cursor could still move: [ 67.742300] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 67.743736] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 1669 at 1372, next 1673) This only happened occasionally, usually when a new window appeared on the screen or when I switched virtual desktops, but most of the time it was fine. I upgraded to 2.6.38-rc3, and it now happens consistently just in the process of logging in. gdm feels laggy, and X locks before xfce finishes loading. It's my first time working with git bisect, but the culprit seems to be this commit: 8fd2685911cb6c140e6d0588ac04990ce65d4537 (drm/i915: Enable RC6 autodownclocking on Sandybridge) If you need me to run with some sort of debugging output to help fix this, just let me know.
