Dell R350, Proxmox VE 8.2.2, sas-megaraid error and system hang

[captaintex]

Hello

Dell R350 with PERC H755.
Tried with kernel 6.8.4, 6.8.8 and 6.5.13.
System hangs (need to phisically power off/on the machine) every day during compressed backup, and sometimes during normal usage of VM.

Log with kernel 6.8.4:

IDRAC reports no errors - Dell support reports no problems.

Have anyone seen something like this before?


Thank you.
