            Bug ID: 93852
           Summary: GPU HANG: ecode 9:0:0x84df7efc
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: falkse at openmailbox.org

Description of problem:
The whole system is freezing, and sound is stopping or repeating.
This happens according to my experience with OpenGL applications like games.
For me, the crash occurs when playing Minetest, Xonotic, Tesseract (all OpenGL
games, only Tesseract not from the Fedora repositories).
Happened after playing about 10 minutes, sometimes immediately after the start
of the game, or sometimes later.

userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
