Hello, FreeBSD-CURRENT/amd64 panics at initialization with this: http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-55.png on a Sun X4550, equipped with two Opteron CPUs and 64 GiB of RAM. The machine will be here for this week, so if somebody can or want to look into this issue, I can test patches.
