Execution stops while enabling MMU

I'm not sure, maybe I got you wrong, but I think that there is no special
configuration necessary. Actually some simple test programs work without
problems, i.e. I can toggle LEDs and write to resp. read from serial
ports. These test programs are running in RAM same way I tried with the
FreeBSD kernel.

What do you want to know? ;-) It's a multi-purpose board with an ARM9
Atmel AT91RM9200 controller, 180 MHz, 64 MB RAM, ethernet, serial ports,
Linux 2.6 preinstalled. Want a picture?

Unfortunately there is no English technical reference available, but I
have a English user guide dedicated for use with Linux:

This is the German technical reference:

There is a huge table on page 6, 7 and 8 that lists the physical address
space (with board specifica) completely. I assume I need to map some more
PA before enabling the MMU.

Thanks
