restbase2009 had a disk replaced as part of T268622. When reimaging, the debian installer kernel panics and the logs note hpsa errors when configuring disks and eventually installation stalls when attempting to create the ext4 fs for md0. a resync is triggered for md0 while the installer is still running.
Errors along the following lines are emitted for all disks:
```

The panic starts as `task md0_resync:20551 blocked for more than 120 seconds`
This could be a problem with the controller firmware or configuration (similar errors were seen in T128107#2234413 //after// the host had been provisioned but without the kernel panics), but I'm not certain about that because restbase2009 had a disk replaced earlier this year which also required reimaging, and this error did not occur.
