Bug 91458

Might be the same as bug #91452, but in my case the crash does not occur randomly but reliably after at most 10min.

dmesg:

[  764.492100] [drm] stuck on render ring
[  764.493303] [drm] GPU HANG: ecode 8:0:0x85dffffb, in X [2336], reason: Ring hung, action: reset
[  764.493307] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[  764.493310] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[  764.493312] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[  764.493315] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
