Hetzner AX101 with enp7s0 network adapter system stability problem on Backup Restoration.

[ValkraS]

Hi to all.
Have been installed 3 servers on Hetzner AX101 dedicated servers from Proxmox 7-1.2 ISO:
2 of them have enp41s0 adapters - Had no problems on reverting even after upgrade
Last one have enp7s0 adapter - If im updating Proxmox to latest 7.1-12 and trying to recover from backup a big VM - Proxmox crashes and goes to reboot. no info in logs just reboot.
Now after some investigations found interesting things:
AX101 servers with enp41s0 adapter have - KIOXIA Corporation Device 0011 (rev 01) KIOXIA KCD71RUG3T84 This One...
AX101 servers with enp7s0 adapter have - Samsung Electronics Co Ltd NVMe SSD Controller PM9A1/980PRO SAMSUNG MZQL23T8HCLS-00A07 This One...

So the problem persist only after upgrade.

UPD: Have this problem again on same server with samsung drives without load.
UPD 2: Same on clean installed system from Proxmox 7-1.2 ISO.
Have only limited zfs.conf to 8GB of ram

You have different mainboards (probably Asus PRO WS 565-ACE and Asrock Rack B565D4-V1L) in your AX101 servers. You can check it with lshw.

You can try to limit max c-state to C1 on affected server. Add processor.max_cstate=1 to kernel parameters.

Thank you mvs for your answer.
I have been cancelled server with enp7s0 network adapter and taken new server with enp41s0 one. (and this one is with samsung NVMEs too...)
All is fine now.
May be some hardware issues on hetzner side, what ever....
