Hi Fabian,
The problem is that you've hard-coded the memory value in the FSConfigs.py
script, but the fs.py script needs the memory value to setup the I/O bridge and
since you've only changed it in one place, the I/O device DMA can't access the
upper 128MB of memory. If you make your change to Benchmarks.py it should work.
