Nan-hai,
OK, the '-noio' option patch you posted on 9/20 was the cause of
my system restart.
http://lists.osdl.org/pipermail/fastboot/2006-September/004062.html
If instead, if i make every inline functions in
purgatory/arch/ia64/io.h null functions, it would then work.
I will attach the patch i used (based on your suggestion) here for
your reference. It was in rough form.
Thanks,
