## Test steps:

1) We first created qcow file by scc by job https://openqa.suse.de/tests/12423401 with iso SLE-15-SP3-Online-x86_64-GM-Media1.iso by SCC and generated qcow file with kernel 5.3.18-150300.59.106 
https://openqa.suse.de/tests/12423401

2) boot from the upper qcow file and do patch_sle with ltss addon, which resulted kernel updated to 5.3.18-150300.59.133


3) reboot and system panic "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)"

## Observation

openQA test in scenario sle-15-SP3-Server-DVD-Updates-x86_64-sle_support_image_gnome_15sp3_basesys-srv-ltss-desk-dev_all_patterns_dev@64bit fails in
[patch_sle](https://openqa.suse.de/tests/12423445/modules/patch_sle/steps/79)

## Test suite description
The base test suite is used for job templates defined in YAML documents. It has no settings of its own.


## Reproducible

Fails since (at least) Build [GM](https://openqa.suse.de/tests/12331542)

## Further details
if we use an old kernel 5.3.18-59.37-default to 
5.3.18-150300.59.133-default, it will pass with the same settings
