freebsd-update panic vm_fault_hold

[Rob Belics]

I was updating my VPS server on a Linux KVM and received this panic:

vm_fault_hold: fault on nofault entry, addr: 0

FreeBSD continuously reboots, which I can see through my hosts Solus
interface, but I'm unable to copy anything from that and I can't login
though I can use the loader.

So I booted into the old kernel and did "freebsd-update rollback" and I'm
back to where I was at p3 but I don't know what to do now unless a bug
report is made.
