David, tks for your attention.
Natty System just started:
~$ cat /proc/interrupts
CPU0 CPU1
22: 234 489 IO-APIC-fasteoi ehci_hcd:usb2, hda_intel
Sound Recorder on and recording (+- 50 seconds later)
~$ cat /proc/interrupts
CPU0 CPU1
22: 444 489 IO-APIC-fasteoi ehci_hcd:usb2, hda_intel
(What usb2 has to do with hda_intel?)
