            Bug ID: 107304
           Summary: [BAT] igt at gem_exec_suspend@basic-s4-devices - fail -
                    fstrim prevents the machines from hibernating
           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: martin.peres at free.fr

On rerun 42/105 of Fast feedback, 20 machines failed the test
igt at gem_exec_suspend@basic-s4-devices. The mysterious thing was that all the
other re-runs of the same kernel configuration passed.

After some investigation from Tomi, turns out it was due to the firing of the
weekly fstrim job.

Suggested W/A are:
 - mount -o discard
 - run fstrim before each run
