--- Comment #23 from Mika Kahola <mika.kahola at intel.com> ---
For my APL with MIPI panel attached I still see a failure on 

./kms_pipe_crc_basic --run-subtest suspend-read-crc-pipe-A

With that test I suspect that the MIPI panel is not getting powered back on
when resuming. The MIPI commands are not getting through to MIPI panel. You can
see the error messages that MIPI video mode commands are failing. This, of
course, leads to failing test case where test case waits for vblank to continue
which never arrives. The test timeouts and fails with vblank timeout.
