8.0-RC2 on Rackmac3,1 - fatal kernel trap

Fri Nov 6 16:51:44 UTC 2009

All-righty, I've got three boot transcripts for you're viewing pleasure.

First, I snagged a copy of 8.0-CURRENT-200906-powerpc-disc1.iso and
burned it. I've removed the ATI video card so this is all done from
the serial console with Open Firmware. Here's the transcript:

Next, being a bored and curious sysadmin, I managed to find that you
had just uploaded 9.0-20091106-SNAP-powerpc-bootonly.iso to your home
folder on people.freebsd.org. I suppose it's premature for me to be
fiddling with it but like I said, I'm bored. :) Here's the transcript:

So there at least I have a debug prompt, but I'm not really sure what
to do with it.

Finally, here's the transcript from the 8.0-RC2 iso:

So, is there any other information I might provide for you?

BTW, thanks for all the help!
