Proxmox Kernel 6.8.12-2 Freezes (again)

[HostingGuy]

Proxmox now provides its own 6.11 kernel. There is no longer a need for the old Ubuntu kernel workaround

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

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

6.11.0-2-pve

installed and if I search for upgrades nothing is found for 6.11 but for kernel 6.8

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:

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.
