Kernel Panic... Can't find console

[De Served <deserved@cogeco.ca>]

I'm attempting to install Debian Sarge on a PowerMac 7200/90.  The
install process works just fine.   The machine reboots without a problem
for a little while, then I get a kernel panic and message saying that
the console cannot be found.   

Here's a link to the dmesg.  I'll update the link the file on the link
as I work around the problem.   This way, I won't have to keep posting
this information.

Anybody have any ideas on how to fix this?   Thanks.
