Bug#745061: libdrm2: [drm] stuck on render ring

Looks like this has been resolved by some update, no hangs for a few weeks. Don't know what the problem was, but the last "[drm] stuck on render ring" entry in the logs is from april 27th:

Apr 27 09:23:53 chieftec kernel: [60145.969920] [drm] stuck on render ring

Apts history log for the 27th contains these upgrades:

The machine was (re)booted at Apr 27 09:25:08. I'm guessing that one of the xserver updates solved the problem.

Severity: important

Dear Maintainer,

Graphics hangs intermittently in Debian testing, this was in dmesg after
several seconds of non responsive graphics:

[ 430.954914] [drm] stuck on render ring
[ 430.954918] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 430.954919] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 430.954920] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 430.954920] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 430.954921] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 430.957326] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo
(0x316e000 ctx 1) at 0x316e004

There are also various graphics issues, e g the mouse cursor often becomes a
square block of lines.

Tried reporting the bug at bugs.freedesktop.org but their bugzilla is
broken(!).

Tried attaching GPU crash dump to this report, wasn't allowed.
