I just compiled a kernel with current sources
CTM_BEGIN 2.0 cvs-cur 1557 1996/01/13 21:00:02
and get an instant panic at ahb probe time:
Kernel from Jan, 6th (before Justin's latest changes on Jan, 7th) is fine.
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x8c
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf0183dd3
code segment = base 0x0, limit 0xfffff, type 1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 0 ()
interrupt mask = net tty bio
kernel: type 12 trap, code = 0
