/sys/class/drm/card0/error

On kernel versions up until 3.12 I experienced frequent hangs of graphical
output for a few seconds each, accompanied by this in dmesg:

Jan  1 00:50:18 inti kernel: [drm] stuck on render ring
Jan  1 00:50:18 inti kernel: [drm:i915_set_reset_status] *ERROR* render ring
hung inside bo (0x4b68000 ctx 1) at 0x4b681c8
Jan  1 00:52:11 inti kernel: [drm] stuck on render ring
Jan  1 00:52:11 inti kernel: [drm:i915_set_reset_status] *ERROR* render ring
hung inside bo (0x5855000 ctx 1) at 0x58551c8

With a current kernel (yesterday's git HEAD, i.e. 3.13-rc6+) I now get this:

Jan  1 18:09:37 inti kernel: [drm] stuck on render ring
Jan  1 18:09:37 inti kernel: [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Jan  1 18:09:37 inti kernel: [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
Jan  1 18:09:37 inti kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Jan  1 18:09:37 inti kernel: [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
Jan  1 18:09:37 inti kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
Jan  1 18:09:37 inti kernel: [drm:i915_set_reset_status] *ERROR* render ring
hung inside bo (0x138b4000 ctx 1) at 0x138b41c8
Jan  1 18:09:37 inti kernel: [drm:i915_set_reset_status] *ERROR* render ring
hung flushing bo (0x139dc000 ctx 1) at 0x138b41c8
Jan  1 18:09:37 inti kernel: [drm:i915_context_is_banned] *ERROR* context
hanging too fast, declaring banned!

Hardware is a Lenovo T520, GPU is an "Intel HD Graphics 3000" according to
Xorg.log. System is Debian Unstable/Experimental. GPU error trace is attached.


Best regards,

Jan
