Is there a way to see where the cpu time is spent when it isn't in userland
?
I took one of our affected systems and killed everything on it as well as
disabling pf.

I suspect that there is some device in there that is being polled in some
funky way
as this only happens on these specific boxes. Even the fujitsu box marked as
"kaputt" with
red marker pen works as charm.
