<pre>Recently I started encountering prblems where my screen will go dark at the
most inopportune moments.
I gathered the following snippet from /var/log/kern.log:
Nov 25 23:34:06 sony-laptop kernel: [ 563.992062] [drm] stuck on render ring
Nov 25 23:34:06 sony-laptop kernel: [ 563.992070] [drm] GPU crash dump saved
to /sys/class/drm/card0/error
Nov 25 23:34:06 sony-laptop kernel: [ 563.992073] [drm] GPU hangs can indicate
a bug anywhere in the entire gfx stack, including userspace.
Nov 25 23:34:06 sony-laptop kernel: [ 563.992076] [drm] Please file a _new_
bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Nov 25 23:34:06 sony-laptop kernel: [ 563.992078] [drm] drm/i915 developers
can then reassign to the right component if it's not a kernel issue.
Nov 25 23:34:06 sony-laptop kernel: [ 563.992080] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
Nov 25 23:34:06 sony-laptop kernel: [ 563.993312] [drm:i915_set_reset_status]
*ERROR* render ring hung inside bo (0x547c000 ctx 0) at 0x547cff0
Nov 25 23:34:06 sony-laptop kernel: [ 564.504051] [drm:i915_reset] *ERROR*
Failed to reset chip.
Nov 25 23:34:08 sony-laptop kernel: [ 565.892050] [drm] GMBUS [i915 gmbus vga]
timed out, falling back to bit banging on pin 2
So in following the instructions I am opening a bug on this :). Since this is
not a problem related to Radeon (I appear to have an integrated Intel GPU),
most other "similar" bugs are not relevant (or do not appear to be).
Unfortunately I have not yet saved the crashdump (/sys/class/drm/card0/error)
so when I rebooted my machine the last dump appears to have been overwritten.
I'll attach a dump when the problem occurs again - assuming I can recreate it.
