Well, i guess it is a x86 SMP documentation stuff, not sure. > most PPCs. If GENERIC_RTC & PPC_RTC doesn't work properly, then we > need to fix the pegasos patch. Well, i use GENERIC_RTC also, but i get a delay when setting the hw clock, maybe even a freeze in older versions not sure. I believe the clock doesn't get set, but i have still to check that. If the pegasos patch needs fixing, i am all for it.
