Thanks, I saw similar info elsewhere. The trick is knowing if the kvm is needed or not. It seems that, for me, irqbypass and ccp use it.
Note that I’ve never seen this problem before, so I presume it was introduced by a recent update. I was hoping to get the answer without having to go through a reboot.
I added the boot parameter kvm.enable_virt_at_load=0, ran update-grub, and re-booted. No joy.
So I ended up doing:
sudo rmmod kvm_amd kvm
Lord only knows what I broke by doing that.
