Multiple tests have a problem with Power On keyword |MSI PRO Z690-A DDR5|MSI PRO Z690-A DDR4|

[wiktormowinski]

Device

MSI PRO Z690-A DDR5, MSI PRO Z690-A DDR4

RTE version

v1.1.0

OSFV version

develop, 3b2a84d

Affected component(s) or functionality

in platform-configs/include/msi-z690-common.robot there is a keyword Power On that makes some tests fail consistently but only while going through the full regression (same tests pass when run individually).

Brief summary

Power On keyword tries to empty the serial buffer on some test cases

How reproducible

it happened to me every single time on 3 separate occasions

How to reproduce

Run regression.sh on any msi z690 and look for any of the tests listed in actual behavior section.
Though, first on the list and the most favorable test subject is CBK001.001

Expected behavior

pass

Actual behavior

many tests get stuck on Power On keyword from platform-configs/include/msi-z690-common.robot
this seemingly random behavor is persistent throughout 3 separate regression runs:

• MSI PRO Z690-A DDR4 with dasharo 1.1.4-rc2
• MSI PRO Z690-A DDR5 with dasharo 1.1.4-rc2
• MSI PRO Z690-A DDR4 with dasharo 1.1.4-rc3

and affects these tests

1. dasharo-compatibility:

• CBK001.001
• EFI001.001
• ESP001.002
• PSF suite

2. dasharo-security:

• EDP001.001
• EDP001.002
• NBA001.001
• NBA002.001
• DMP001.001

3. dasharo-performance
   nothing.

Additional context

at first I thougt it may be caused by empty buffer but the aforementioned individually run test cases seem to have no problem with that:
