So much for the race idea. We put some code
into the kernel to make sure this can't happen.
I'm about to build a new boot disk and we can
go from there.

Hi
I tried again and got about the same [lines that were different were
modified and leading '> ' was removed]:

Also, what may not have been clear from my earlier mail was that I dual
boot [into the dreaded win98se]. Also, my floppy drive has been acting
up- is there anything here that might represent a hardware failure on
that account?

Start the install over. I bet it doesn't happen again.
(Yes, this is a terrible answer. I see what happened
and can't figure out how it did, but I suspect it's
just a really nasty race, and the fact that we haven't
seen it anywhere makes me hope that it's just a
really difficult race to trigger.)

Hi
I had a working plan9 install, then I was foolish enough to use and try
to maintain [windows update, &c]. Of course, it crashed at one point and
during this 'unexpected behavior' somehow the boot thing got all messed
up. When trying to boot plan9 it complained of 'command or file not
found' [something like that].
So I was going to reinstall, I wanted to update my sources anyway since
they came from the old CD iso. It booted off the floppy, found the
ethernet card and while rio was initializing- BAM! It was over.
Here is what I copied down from the screen:
cpu0: registers for stats 103
FLAGS=10246 TRAP=0 ECODE=8010034D PC=801537FD SS=E1C8 USP=0

CR0 80010039 CR2 00002dfa CR3 01423000 CR4 00000010
ur 8063cad4 up 802d0c48
panic: divide error
ktrace /kernel/path 80106720 8063c8e8
Any suggestions?
