I'm trying to use code into sleeper.S from kernel 2.4 but I still have
a problem. The system corrctly wake up and linux restart but the
problem is that after about 600-800mS the system hangs! I've just the
time to press 2 or three times the enter key and see the console
prompt.

I've checked also the interrupts from TOY and I noticed that it stop
working!

Has anybody used the sleep mode for Au1xxx processor? Which version of
sleeper.S file has been used?

Thanks in advance,

Rodolfo
