I'm running amd64 SMP -current around Dec 14. It seems that I can reproduce
this panic by 'mergemaster -iU' at /usr/src reliably.
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x68
fault code = supervisor read data, page not present
instruction pointer = 0x8:0xffffffff802e0ce3
stack pointer = 0x10:0xffffffffa0019510
frame pointer = 0x10:0xffffffffa0019570
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 786 (mtree)
Due to no remote console attached, the console ddb backtrace
is available at flickr:

I put my kernel conf and kgdb output here:

I saw there is another report on @hackers this Oct. But it seems
the originator solves the problem by upgrading to latest RELENG_6.
Any suggestions? I can provide more information if someone interested.
