I think Bengt Nolin in the first page is reporting something like this.

Our problem has been a headache in our tests today :) I asure you it is 
there, and it is fixed downgrading kernel.

I don't know why it's happening, but VMs' clock seems to broke suddenly 
and spectacularly... :)

Nodes have Ryzen CPUs, and storage is Ceph. Network is 10G for 
Ceph/migrations, 10G for VMs/cluster.
