I get a panic while booting with the release cdrom I built from RELEASE_1_2 tonight, both in default and safe modes:

panic: pmap_bootstrap: no local apic!

mp_lock = 00000000; cpuid = 0; lapic.id = 00000000





Fatal trap 12: page fault while in kernel mode

mp_lock = 00000000; cpuid = 0; lapic.id = 00000000

fault virtual address = 0x0

fault code = supervisor read, page not present

instruction pointer = 0x8:0xc03c3f4b

stack pointer = 0x10:0xc0657b9c

frame pointer = 0x10:0xc0657b9c

code segment = base 0x0, limit 0xfffff, type 0x1b

processor eflags = interrupt enabled, IOPL = 0

current process = 0 (thread0)
