That looks like bad RAM or a similar hardware problem, because they aren't the same panic.

If you have the FreeBSD sources loaded, try doing:

(assuming root permissions and csh, as obtained by "su" in a default config)
YourPrompt# cd /usr/src
YourPrompt# repeat 5 make buildworld buildkernel

This will take a long time (if it doesn't crash); let it go overnight or something.  If it consistently crashes, then you almost certainly have a hardware issue of some sort.
