            Bug ID: 90994
           Summary: [BDW regression] pm_rpm subtests fail and give WARNs
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: przanoni at gmail.com
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
                CC: intel-gfx-bugs at lists.freedesktop.org

Steps to reproduce:
- Boot BDW on -nightly
(I currently have eDP + HDMI + DP attached when I boot, but that shouldn't
matter)
- sudo ./pm_rpm --quick
- see all the failures
- check for the dmesg WARNs

Expected results:
- All tests pass
- Not a single WARN or ERROR on dmesg

Both the WARNs and test failures are regressions. I'm 100% sure that a few
months ago we were passing every test without any WARNs. So these current
problems are actual regressions.

As far as I remember, thee "dpms" subtest failures are _very_ recent, so it
should be fairly quick to bisect them.

Why didn't we catch these regressions with PRTS?
Why didn't we catch these regressions with nightly testing?
