Hi Everyone,

Recently I'm having random reboots with my environment

Enviroment hardware details(2 x Dell R6525):
AMD EPYC 74F3
BCM57414 NetXtreme-E 10Gb/25Gb RDMA Ethernet
PERC H745 (with raid 5 and 5x3.84ssd 12g)
Fully updated (bios/network/idrac/sas)

Proxmox:
Proxmox 7.1.8
Kernel 5.13.19-2-pve

I contacted dell support, we did a log survey and they assured me that it is not a hardware problem (I believe it is only because it happens on another server exactly like this one)

looking for the logs found this (kern.log):

I would like to know if there are other cases like this because it happens on other servers and if there is any suggestion of correction or workaround.
