I actually do have control of my qemu in proxmox, and sure enough removing = the virtio rng device fixed the problem, am running multiple 12-STABLE Guests t= hat do not have this problem. I looked at kern.random and compared to the 12-STABLE VM's, and the key difference is that the virtio device is available and activated in 13, whil= st it isn't even listed as available in 12. So it works on 12 because it isn't used. --=20 You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.=
