See the thread about "Page faults from bento cluster (Re: Problems reading
vmcores)]" which seemed to diagnose this. The last mail that I got about
this pointed to:

As a workaround, try unmounting most of your filesystems from userland
using umount -A. Don't use umount -f. (There seems to be a problem
with the MNT_FORCECLOSE case in vflush(). MNT_FORCECLOSE is set more than
I thought: it is always set for the final unmount done by reboot(2)).
