I've been trying to get a recent NetBSD running on my wife's old G4/466, and
was able to get 2.0.2 installed from the 'offical' CD finally.

However, the main thing I want to do on this box is test stuff on -current
and newer branches like netbsd-2 and netbsd-3, so, I tried booting a -curre=
nt
kernel, and BOOM.  So, I tried an up-to-date 2.0_STABLE kernel from an
up-to-date netbsd-2 branch, and BOOM, in exactly the same way.  :(

Here's the crash message, in a ten-finger copy:

[...boot messages...]
atapibus0 at atabus1: 2 targets
trap: pid 3.1 (atabus1): kernel MCHK trap @ 0x518e0c (SRR1=3D0x2041020)
panic: trap
Stopped in pid 3.1 (atabus1) at netbsd:cpu_Debugger+0x18:	lwz	r11, r1, 0x0
db>


=2E..and there I'm stuck; the keyboard doesn't work, and I don't have
a serial console (any way to use a USB->serial dongle as one?), so there's
no further debugging information to give.

Before I start a binary search of the netbsd-2 branch to figure out which=
=20
pullup broke me, does anyone have any suggestions?  Below is as much of the
boot messages as got saved in the buffer between reboots (there was more at
the end, culminating in the panic above).  (Note the "0.01 MHz" CPU - should
I worry? :)
