Hello team,

something in the product must have changed as over hundred tests are now failing on fs-probing. Example is here https://openqa.opensuse.org/tests/3673763#step/yast2_bootloader/5

I did ask Oliver if he is aware of any issue on openQA that could trigger this and he thinks this must be a product change.

The issue did not happen week ago. And the bootloader stack is taken/inherited fully from SLES.


## Observation

openQA test in scenario opensuse-15.6-DVD-x86_64-upgrade_Leap_15.2_kde@64bit fails in
[upgrade_select](https://openqa.opensuse.org/tests/3673823/modules/upgrade_select/steps/4)

## Test suite description
Upgrade scenario from Leap 15.2 with kde installed.	



## Reproducible

Fails since (at least) Build [507.2](https://openqa.opensuse.org/tests/3505084)


## Expected result

Last good: (unknown) (or more recent)


## Further details

Always latest result in this scenario: [latest](https://openqa.opensuse.org/tests/latest?arch=x86_64&distri=opensuse&flavor=DVD&machine=64bit&test=upgrade_Leap_15.2_kde&version=15.6)
