* CHAMELIUM: igt@kms_chamelium@hdmi-cmp-planes-random - fail - Failed assertion: ret == 0
Hit every 2 weeks. Affects KBL and now ICL too.
User impact: we are not able to check multiple planes work with the Chamelium board. I believe this is a test issue, picking an invalid configuration by mistake.
I'd suggest doing an atomic TEST_ONLY commit before the actual commit (and skip/reroll dice on EINVAL).
Could not access the detailed logs for the failure.
Link for page mentioned in description and in comment 1 do not exist.
Can i get the logs please?

Igt Log on IceLake
I tested kms_chamelium subtest hdmi-cmp-planes-random and it is executing successfully on both IceLake and KabyLake.
On IceLake test is skipped sometimes but not able to reproduce.Failed assertion: ret == 0.
Issue seems to be with .igtrc files or chamelium dependencies not installed.
I have attached the logs.
