Is interrupt flooding the only issue or are there other ones?

Is it caused by ACPI only?

Is it specific to SMP or does it happen in UP too?

Do we know if people who experience these problems have better luck
with other OSes (BSD or not) and if so what are these OSes?

Or phrased differently: Is porting interrupt routing code from another
OS (taking into account DF specificities) a good strategy?  If so
which BSD is best?  I read in the archives Matt stating that there are
stilll problems in fbsd and IIRC  someone else mentioning NetBSD as
being better at this.

Cheers,
