kernel trap 12 with interrupts disabled
panic: vm_fault: fault on nofault entry, addr: c9f7c000
...
calltrap() at calltrap+0x6/frame 0xc1820c9c
--- trap 0xc, eip = 0xc1820d37, esp = 0xc1820ce8, ebp = 0 ---
end() at 0xc1820d37

First thing is to try to identify what is the code was executing there.
Try to disassemble some amount of instructions before and after the
faulting %eip.
