I'm attempting to boot a 1.5.2 kernel over the network and while it
appears to be doing that, when it starts to run it dies with a VMEbus
exception. Here's the console output:

Booting from tape yields the same results.

I'm at a loss as to what to look at at this point. The J1 1-2
jumper is off, but this error occurs with it on as well. There
are no other boards in the chassis.

This board has 32MB of RAM which passed the diagnostic tests
and the ENV parameters are set to the defaults, except for the
"Network Auto Boot Config Param Pointer which is set to FFFC0200,
although the default for this value (0), didn't effect the
exception either.

Any suggestions ?
