Hi,

I've just got back from holiday :))) so have only just seen
this thread.

This exact behaviour occurs on an arm610 riscpc. I reported
it some time ago and isolated it to the same place (in
cpu_func_asm.S). Mark B. has reproduced it, but I don't know
if he's had time to look at it yet.

I doubt if it's your memory configuration. On my machines,
swapping the processor to a strongarm(I only have one
between 2 RPC's) boots fine.

If you find a solution, please let me know!
