GPU crash dump from /sys/class/drm/card0/error
Dmesg shows the following when comming out of powershave (screensaver). Unsure
what caused this, but the dmesg told me to file a bug report here, including
attaching the crashdump.
[ 8835.191819] intel_powerclamp: Start idle injection to reduce power
[ 8867.237426] intel_powerclamp: Stop forced idle injection
[ 9035.893149] intel_powerclamp: Start idle injection to reduce power
[ 9069.214468] intel_powerclamp: Stop forced idle injection
[ 9341.965675] [drm] stuck on render ring
[ 9341.966371] [drm] GPU HANG: ecode 6:0:0x94eeffb8, in compiz [18008], reason:
Ring hung, action: reset
[ 9341.966372] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 9341.966373] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 9341.966374] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 9341.966374] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 9341.966376] [drm] GPU crash dump saved to /sys/class/drm/card0/error
