--- Comment #30 from Arek Hiler <arkadiusz.hiler at intel.com> ---
After the patch got merged it seems like the only offender during the last week
was kms_flip at 2x-dpms-vs-vblank-race on cml-u2.

https://intel-gfx-ci.01.org/hardware.html#fi-cml-u2

cpu: Intel(R) Core(TM) i5-10210U CPU @ 1.60GHz
gen: 9
display:
  eDP-1:
    status: connected
    display: SHP LQ133M1JX34
  DP-1:
    status: connected
    display: STM AthenaDP
  DP-2:
    status: connected
    display: STM AthenaDP
  HDMI-A-1:
    status: disconnected

DP-1 and DP-2 are connected to Chamelium (STM AthenaDP is the default values of
the EDIDs for the DP receiver it uses), which means that under some
circumstances it may have all the ports disconnect (e.g. after Chamelium
reboots, it's the default state). This is indeed the case
(https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_340/fi-cml-u2/igt@kms_flip@2x-dpms-vs-vblank-race.html):

2x tests require two displays, so it skip. I expect seeing more 2x tests
failing occasionally.

The impact on the users is none, it's purely CI/HW limitation. Simon Ser is
working on making sure that the default Chamelium state in our CI is connected.

For now I would recommend changing the bug to cover only the 2x tests.
