There is a bug with STM^ on the early SA110s - you must have a rev K one
(it's fixed in rev S and T, the other two common ones in Risc PC processor
cards). Rev K SA110s are ancient history as far as ARM is concerned, I doubt
they'll have had many customers other than Acorn.
If you look at the kernel sources, you'll see exactly the same workaround in
a few places.
