            Bug ID: 93640
           Summary: [BAT SKL regression] Fifo underruns since CI_DRM_952
           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: daniel at ffwll.ch

Build 951 was somehow fail on the affected snb machine, so unclear where
exactly the regression is.

Machine name is snb-dellxps. Affected testecases (from a quick look 100%
reproducible):

igt at kms_pipe_crc_basic@suspend-read-crc-pipe-b
igt at kms_pipe_crc_basic@read-crc-pipe-b
igt at kms_flip@basic-plain-flip
igt at kms_flip@basic-flip-vs-wf_vblank
igt at drv_module_reload_basic

Assigning to Matt Roper since most likely this is fallout from the wm rework.
