Summary: stuck on render ring at seemingly random moments.

Severity: major
Classification: Unclassified
OS: Linux (All)
Reporter: robert2505 at gmail.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: XOrg 6.7.0

Dump from /sys/class/drm/card1/error
The system hangs for a few seconds, then dmesg spews this:
[ 197.405192] [drm] GPU crash dump saved to /sys/class/drm/card1/error
[ 197.405193] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 197.405194] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 197.405195] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 197.405196] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 203.441104] [drm] stuck on render ring
And the system continues.
Untill reboot random glitches (mostly white bars and blacked out textboxes)
appear
Also, around the time this started happening, bumblebee started rendering black
windows when using Primus as a bridge. VirtualGL looks normal.
Primus can be fixed by setting environment variable PRIMUS_UPLOAD=1
