          Priority: medium
            Bug ID: 76554
                CC: intel-gfx-bugs at lists.freedesktop.org
          Assignee: intel-gfx-bugs at lists.freedesktop.org
           Summary: [gm45 regression] [drm:init_ring_common]: *ERROR*
                    render ring initialization failed
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: jikos at jikos.cz
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: DRM/Intel
           Product: DRI

This is not reliably reproducible, so not possible to do proper bisect.

There are suspend-resume cycles which end up with Xorg misbehaving (graphics
not redrawing properly, etc), and dmesg contains

[drm:init_ring_common] *ERROR* render ring initialization failed ctl 0001f001
head ffffff8804 tail 00000000 start 000e4000

This is both with current Linus' tree (HEAD 774868c70) and the issue is still
present even after merging drm-intel-testing (HEAD 14347c2) into it.

There is currently ongoing mailinglist discussion here:
