GPU crash dump
I upgraded a stock Debian Wheezy system kernel to a vanilla 3.16.3 downloaded
from kernel.org and my system was slow to boot. My logs showed a 3 minute hang
before printing this message:
Sep 29 12:57:16 notleych-linux org.kde.powerdevil.backlighthelper:
QDBusConnection: system D-Bus connection created before QCoreApplication.
Application may misbehave.

Sep 29 12:57:22 notleych-linux kernel: [ 198.749260] [drm] GPU HANG: ecode
0:0x85fffff8, in kwin [3405], reason: Ring hung, action: reset
Sep 29 12:57:22 notleych-linux kernel: [ 198.749263] [drm] GPU hangs can
indicate a bug anywhere in the entire gfx stack, including userspace.
Sep 29 12:57:22 notleych-linux kernel: [ 198.749264] [drm] Please file a _new_
bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Sep 29 12:57:22 notleych-linux kernel: [ 198.749265] [drm] drm/i915 developers
can then reassign to the right component if it's not a kernel issue.
Sep 29 12:57:22 notleych-linux kernel: [ 198.749266] [drm] The gpu crash dump
is required to analyze gpu hangs, so please always attach it.
