-current under Xen

  After bruce C gave me the hint of kern.eventtimer.periodic=1, I was 
able to boot -current on my vps
at rootbsd.com, but it hangs on reboot.. some time before the unmounts 
as the
file systems need to be cleaned on the next successful boot.
Has anyone had any experience with this?

unfortunately I can't yet tell you the version of Xen in use there.
