            Bug ID: 93297
           Summary: [BAT BYT] timeout waiting for GFX clock force-on
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: joonas.lahtinen at linux.intel.com

When running the BAT test basic-rte at pm_rpm, the following problem appeared.
Could QA confirm this by running the test in a loop and observing the results.
After first failure, further test executions fail immediately due to runtime
resume getting disabled.

This was after a long session of debuggin other problem, so not attaching the
full kernel log.
