I could never finger the problem be it with bios, the actual memory, or the fact that there's only one 4 core cpu on a two socket board and only the associated memory bank filled. I did various memory swaps to no avail, it would run memtest86 all day with no errors, and in the end I just turned superpages off and it works . Like a champ. If vm.pmap.pg_ps_enabled is 1 in 8.0-rc2, you might try rebooting with vm.pmap.pg_ps_enabled="0" in /boot/loader.conf and try another buildworld.
