GPU crash dump
Hi,
since updating to Linux 4.4 I'm repeatedly experiencing this bug, but can not
reliably reproduce it. It usually appears in random intervals after using the
computer for a few hours.
dmesg:
[drm] stuck on render ring
[drm] GPU HANG: ecode 7:0:0x85fffff8, in Compositor [13633], reason: Ring hung,
action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
