Hello,

I'm in the process of porting a PCI-driver for a dsp-board from 2.4 to
2.6. The probing of the driver goes well, IRQs are setup, resources
are claimed and remapped without any problems. Reading from I/O
regions also works well. However, when i try to read or write to a
memory region using readl/writel, the system instantly hangs. No
stacktrace or anything, it just stops.

Hmmm.  Not good.  Are you able to access the memory regions from the
U-Boot console?
