I have no idea what 4.5-p4 is. Is it RELENG_4 (stable) or RELENG_4_5
(the security branch), and what was the build date?
The reason I am asking is that there was a bug fixed sometime during the
4.5 cycle where a VM object could be freed while still holding pages
undergoing I/O, resulting in this sort of panic. The fix is not a
simple one-liner, however, so if this is what is causing your problem
the best thing to do is probably to upgrade to the latest -stable.
