NetBSD biko 1.6ZG (DELLI8K) #1: Sat Dec 27 12:19:05 EST 2003 root@biko:/usr/src/sys/arch/i386/compile/DELLI8K i386
>Description:
I've built a generic + ieee1394 kernel in an attempt to get an external
Maxtor firewire drive working on netbsd-current.  This is on a Dell
Inspiron 8000 laptop.  I recall this setup working (although a bit
buggy) several months ago with the ieee1394 code in current.  Now when I
attach the device I get a kernel panic (on boot) of the following:

fw0 at fwochi0: 46:4f:c0:00:12:84:d4:01:0a:02:ff:ff:f0:01:00:00

kernel: page fault trap, code=0
Stopped in pid 3.1 (fwohci0) at netbsd: sbp2_abort+0x49: movl 
%ebx,0xec(%edx)

After being dropped to db, here is the backtrace:

If more information is needed to determine the cause of this panic let
me know and I'll do my best to provide it.


>How-To-Repeat:
Attach an external firewire disk to the system after building a kernel with ieee1394/sbp support.
