Panics when using IDE

[John Klos <john%ziaspace.com@localhost>]

Hi,

I've got a serial console on my Quadra 630 finally, so I thought I'd post 
a panic in case anyone can help figure out how to start fixing this.

Panics occur with GENERIC kernels from HEAD (I've tested up to two days 
ago), NetBSD-5.1RC2, NetBSD 5.0.2, and from netbsd-5 from a day or two 
ago. I have a -current kernel from 31-December-2009 which works.

This happens whether I try to start in single user mode or multiuser, and 
when I start it in single user mode, it'll get to the point where it asks 
for a shell, pause for a second or two, then panic.

If I tell the booter to ask for root/dump devices, it allows me to enter 
everything up to and including /sbin/init, but panics after a second or 
two of sitting and waiting for me to enter the shell:

init: trying /sbin/init
Enter pathname of shell or RETURN for /bin/sh: trap type 1, code = 0x0, v 
= 0x42
kernel program counter = 0x153356
