I see this as well, and am not using the CAN bus. I have killed most of the
daemons running, apache, inetd, etc. still the pauses continue, and top does
not reveal any culprit.
It DOES sometimes seem like it is on the console or terminal (ssh) that the
problem is the worst. Running application seem less prone to the dead spots.
I have tried playing with the nice settings, but the problem persists on
terminal and ssh
