Power On on MSI z690 ddr5 not powering on reliably

[philipandag]

Device

MSI z690 ddr5

RTE version

OSFV version

540-reset-to-defaults-restore-serial

Affected component(s) or functionality

dasharo-compatibility/cpu-core-count.robot: CCC test case. Most probably any other case that reboots the platform multiple times too.

Brief summary

The platform sometimes simply does not power on after the keyword

How reproducible

~50% on single tests. The whole CCC suite will surely experience at least one fail

How to reproduce

Run the CCC test suite

Expected behavior

The platform should always power on after the Power On KW as multiple tests rely on that

Actual behavior

It sometimes simply does not power on. In the failed test cases the platform is turned off after the Power On keyword, which was determined with the lack of video output on PiKVM. Powering it on manually using osfv_cli rte pwr on after the Power On keyword fails to do so results in the platform booting normally and the tests continuing.

Additional context

I have no clue why it wouldn't work looking at the implementation of the keyword in msi-z690-common. Maybe the sleep times are just too short?

I have re-run the suite increasing the timeouts in the Power On significantly (10s and 15s) and the whole suite has passed. Solving the issue is just a matter of choosing a less overshot sleep durations.
