For the record:
While building some ports I got the following panic:
(6.0-CURRENT, UP, SCHED_ULE)
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x50
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc056ecfd
stack pointer = 0x10:0xd9978c68
frame pointer = 0x10:0xd9978cec
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 44 (pagedaemon)
trap number = 12
