I'm having similar problems: Some minutes/hours (depends on the workload) after each boot 'top' reports about 12% of my CPU time are used for interrupt processing. The interrupt time stays at about 10% even when there's nothing to do (no disk io, no network traffic, no sound). Running FBSD 4.2 on the same box reports about 0.2-1% interrupt usage; the same value which is shown on CURRENT just after a reboot. At the same time the packet loss rate of my isdn interface raises to about 70% while transfering files. (a simple ping does *not* trigger this problem). This behavior seems not related to rtprio oddity since i first noticed it on Apr 9th.
