I notice it got through all the device identify stuff. It dies as soon
as it actually tries to tranfer a real block of data (the partition map)
and do something useful with it. Could you see if disabling PDMA helps?
There's a way to do it with the command line, but that is messy. If you
don't mind recompiling, just set the FLAG_NO_PSEUDO_DMA flag like it
always does for the IIfx case. The performance will be terrible, but
it might help narrow down the problem.
