SubjectRe: APIC errors and aic7xxx interrupts w/SMP on 2.3.25

I'm not getting them on 2.3.26... I'll keep watching it though.

My machine (bp6 celeron dual) has APIC error and strange SCSI
interrups.
I don't know the relations of those.

I have the same APIC error messages as above.

Another problem is on aic7xxx.

/proc/interrupts saids the SCSI driver produces massive interrupts,
about 17000 interrupts per second for each CPU even if no SCSI
devices are attached.

The SCSI I/F(2940UWD) is a dual channel SCSI adaptor, only one of the
channel produces interupts.

This happens on 2.3.25 but not on 2.3.18.

Does anybody tell me a clue?
