Thanks.

I was looking for what APIC mode and it was a PIC/IO-APIC interrupt.

So it looks like it is using logical flat mode and the interrupt was
from IO-APIC.

So most likely on your system after a successful boot, if you manually
set the affinity of one of those SATA/PATA interrupts to a specific
logical cpu say 0, I think the interrupt still get routed to other
logical cpu's. Can you confirm?

thanks,
suresh
