Hello,

I am using an 8275 and map memory.
When I map my LEDS physical 0x40000000 to 0x40000000
using a BAT I can hit them, several minutes into execution
during a sync, the system hangs.

I have tried to map this to a smaller region using the
mmu (io_block_mapping) but when I do the
region is no longer accessable.  THis is the
preferred method as I have a large region at
3000.0000 that I want to map using the remaining
BAT.

What should I do?  Any clues where to search for
an explaination of what is going on?


Thanks
Kevin
