Random crashes of the Proxmox VE

[LukasAdmin]

Randomly I get some messages on the screen and I am unable to reach via web the GUI.
The messages are like these:

ignored rdmsr
ignored wrmsr

But from my research I think those are not errors, just warnings.
The other messages I get is even weirder:

vcpu6, guest rIP: 0xfffff80106ff7712 kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x1, nop

Repeated a bunch of times with differente values of vcpu's.

Can anyone help me? I am running the latest kernel available and this is the relevant hardware:
- GA-7PESH2
- 2 GPU passed through to VM's

EDIT:
I am also running my VM's disks on another machine direct connected via ISCSI.

Both messages are normal. What exactly happens when the system becomes unreachable? Does only network connectivity go down? Does the entire box hang (i.e. can you still type commands physically)? pveversion -v?

Note that GPU passthrough can lead to instability at times, maybe try running without that for a while and see if that makes a difference.

Yes the entire box hangs, this just happened when I moved to PVE 7.

Could you try rebooting the machine and choosing a different kernel version on your bootloader prompt? It may be a regression in the new 5.11 kernel.
