I just recompiled the kernel with the sources dated
CTM_BEGIN 2.0 cvs-cur 1439 1995/12/13 15:00:03
and got the following panic:
fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:f0161fcf
code segment = base 0x0, limit 0xfffff, type=0x1b
= DPL 0, pres 1, def32 1, gran 1
processor flags = interrupt enabled, resume, IOPL = 0
current process = 0 ()
interrupt mask = net tty bio
kernel: type 12 trap, code = 0
