I've run into the ed0 bug with the 3c503 in version 2.2.1 a number of
times.  What
is happening is that unlike all of the other ed0 cards the driver supports,
the
3C503 can be set to use shared memory mode with jumpers.

Unfortunately, if the ed0 driver doesen't have memory-mapped mode turned on
and the card is in this mode the machine will crash with the error.  This
is true
even if you go into visual mode and change the driver settings.

What I've done to fix this is to install the machine will no networking
turned on, then recompile the kernel with the proper memory settings
defined for the network card.

I don't know why the GENERIC kernel was compiled with ed0 having no defined
memory region, but it sure wreaks havoc on 3C503 cards during the
installation.
