--- Comment #5 from Imre Deak <imre.deak at intel.com> ---
The patch in comment#1 seems to fix the issue:

  * igt at kms_flip@basic-flip-vs-dpms:
    - {fi-icl-u3}:        [DMESG-FAIL][13] ([fdo#110718]) -> [PASS][14] +1
similar issue

  * igt at kms_flip@basic-flip-vs-modeset:
    - {fi-icl-u3}:        [DMESG-WARN][15] ([fdo#110718]) -> [PASS][16] +1

Before posting the patch I'd like to test if it fixes the problem consistently
when triggering the issue with Chamelium tests. I think the workaround only
works on ICL D2 stepping (like the ICLs in CI).
