            Bug ID: 94927
           Summary: [drm] GPU HANG: ecode 9:0:0x85dffffb, in compiz
                    [1755], reason: Ring hung, action: reset
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org

Possible duplicate of #94464, but filing just in case.

After logging into my Ubuntu 15.10 system, I get some blocky grpahics glitches,
then a long stall (where the following message is printed to dmesg), then it
will sometimes recover for a few seconds then another stall, with more
messages, over and over. Eventually the system will crash hard and I've not
been able to capture that log.  

Warning in dmesg:

[   18.898605] [drm] stuck on render ring
[   18.899840] [drm] GPU HANG: ecode 9:0:0x85dffffb, in compiz [1755], reason:
Ring hung, action: reset
[   18.899847] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   18.899851] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   18.899855] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   18.899858] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
