I don't think the RTC should be involved here, because I may not have
a RTC on the production board. I do think it is the timer interrupt,
but why do I (the BIOS) have to setup the timer interrupt when linux
is doing this anyway the way it needs it ?
I checked the southbridge code and tested it, but no effect.
First I tought it is some specific STPC init missing, because when
I have a look at other bootloaders, no further init of this is done
and the kernel has no problem. But if it were a STPC specific
init problem, how can the standard kernel do it during further boot ?
So I'm really confused here.
