Hi Martin,

meanwhile, some more people who face the same problem have been gathering in this thread 
in the Proxmox user forum:

https://forum.proxmox.com/threads/pve-8-2-kernel-6-8-4-2-does-not-boot-cannot-find-root-device.145764/

Two of them also have an Adaptec controller, while another one has a PERC H310 Mini (LSI 
based).

Did you have any chance to look into this in more depth? Do you need more information from 
me to tackle this issue? I'm not a kernel developer, just a user, but I guess with proper 
instruction I would be able to compile and test patches.

Beste Grüße,
Peter Schneider
