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. (the date this box switched to CURRENT)
