Bug ID: 93768
Summary: [BAT SKL] GPU death starting with first symptom:
WARNING backtrace: "DC6 already programmed to be
enabled."
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: mika.kuoppala at intel.com
QA Contact: intel-gfx-bugs at lists.freedesktop.org
CC: intel-gfx-bugs at lists.freedesktop.org
With two runs as of now:
archive/results/CI_IGT_test/CI_DRM_985/skl-i7k-2/
archive/results/CI_IGT_test/CI_DRM_974/skl-i7k-2/
the gpu as become unusable (failed initialization hanging always all
rings except render).
The first symptom is warning about dc6 is already enabled, then the problems
mount up flips start to fail:
