Proxmox Kernel 6.8.12-2 Freezes (again)

Yes, I've already opted-in with it, but didn't check its work yet.
And 6.11.0-1 quite first release, then 6.11.0-9/12 :D
 
Had to back to 6.11.0-9, with 6.11.0-12 got hangs again.
6.11.0-13 need to be tested also and pve-6.11.0-1.

how did you do go back to 6.11.0-9?

I have 3 nearly identical hardware hosts in one cluster - but one is crashing with kernel 6.8; updated to kernel 6.11 for proxmox and rebooted, but still crashing - I have
Code:
6.11.0-2-pve
installed and if I search for upgrades nothing is found for 6.11 but for kernel 6.8
Code:
proxmox-kernel-6.8/stable 6.8.12-5 all [upgradable from: 6.8.12-4]

I'm running on Supermicro hardware with AMD EPYC 7513 CPUs. Really annoying :(

The only HW difference might be the network cards:

Code:
root@crashing-server:~# lspci | grep -E -i --color 'network|ethernet'
01:00.0 Ethernet controller: Intel Corporation Ethernet Controller X550 (rev 01)
01:00.1 Ethernet controller: Intel Corporation Ethernet Controller X550 (rev 01)

81:00.1 Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01)

root@working-server:~# lspci | grep -E -i --color 'network|ethernet'
44:00.0 Ethernet controller: Intel Corporation Ethernet Controller X710 for 10GBASE-T (rev 02)

I replaced the network card from crashing-server today* - before the replacement I also had random (no specific time) crashes - even with no VMs running on the host. Now time will tell if this worked - if yes I'd be more than happy. If I don't update this post for any reason this solved my issues.

Code:
root@crashing-server:~# lspci | grep -E -i --color 'network|ethernet'

* Intel X550 PCIE (AOC-STGS-i2T on a regular PCIE riser AOC-2UR668G4) was replaced by a Intel X710, special Add-On Card for my Supermicro Mainboard AOC-2UR68G4-i2XT
