Badness at c021e700 [verbose debug info unavailable]
it would be helpful to compile a kernel with verbose fault information
turned on.
Doesn't seem to provide too much more info on ppc. just says the file/
line number of the badness.

Looks like you're running into the same problem as I did, with the
fact that the M5529 is in native mode, but doesn't have any IRQ
available. Do you know if the bridge chip in it is in routes the
IRQs internally?
They are routed via an i8259 in the bridge.
