Hi,
at least one of your panics seems related to the recent changes in
kernel virtual address allocation.
(namely, http://www.lerctr.org/~ler/FreeBSD/core.txt.3).
You can try revert the revision that introduced them and see if this
stabilizes things. Just a guess though.

http://svnweb.freebsd.org/base?view=revision&revision=254025

Thanks,
