Actually, I never went back to (en)abling the peripherals in BIOS. I'll
wait untill I finally find the culprit and then enable them and see what
happens. So this reflects my current situation...

During bootup, I see mentions of S88rtirq, so I looked and I see there
is '/etc/rc.d/rc3.d/S88rtirq'.

While recording with ecasound (with realtime privileges) and running
'jackd -v -R -dalsa -r48000 -p512 -n2 -D -Chw:2 -Phw:2'... during the
interruptions, I received these messages...
(I get interruptions with every combination of periods and buffer sizes
I've tried)

Thanks... keep the suggestions coming. I'm not going to settle for this
as the result after investing 5 years into Linux/Audio.
