hi, David,

sorry that we only have initial support for fedora
https://github.com/intel/lkp-tests?tab=readme-ov-file#supported-distributions

we will look this issue. however, due to resource constraint, we may not be
able to supply quick support.

btw, for this case, it really need 4 hdd partitions, so need refer to
https://github.com/intel/lkp-tests?tab=readme-ov-file#run-your-own-disk-partitions
