I'm getting frequent GPU hangs. It looks like somehow google chrome is either
the cause or a "catalyst" of the bugs, because the bugs occur after I have a
lot if chrome tabs opened. I'm running Debian "sid". The hangs were occurring
on linux 3.14, causing a lot of problems, and I was unable to start chrome
after such hangs until the system is rebooted. After upgrading to linux 3.16,
I've got the following message in the log (but chrome appears to be usable
without a reboot):
[101452.978884] [drm] GPU HANG: ecode -1:0x00000000, reason: Command parser
error, iir 0x07fcc000, action: continue
[101452.978888] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[101452.978890] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[101452.978891] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[101452.978892] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[101452.978894] [drm] GPU crash dump saved to /sys/class/drm/card0/error
I'm attaching the contents of /sys/class/drm/card0/error
Hopefully someone will be able to fix this nasty problem.</pre>
