Kernel panic ?

[tlex]

I hate doing so but I tried understanding as much as I could what was going on with one of my hosts and I don't get it.
Since a few weeks the host will crash with the following message on screen randomly. Sorry for the poor copy paste, this is from a picture taken on iphone.
I really don't know were to look for. I've tested my ecc ram and no errors on this side. checked the disks, no error as well. Do you have any suggestions ? the system is up to date.

I'm getting the same error also, CPU 1 kvm tainted. same version of proxmox also.

Perhaps a bug with the release?
