Interrupt latency problems

[David Leimbach]

I had a problem like this as well when I wasn't using /dev/sysmouse as
my mouse driver way back in FreeBSD 4.3 or 4.4... I don't remember 
which.

Make certain your configuration uses the native FreeBSD mouse driver and
that moused is running.

I know its a weird solution but it really worked for me back then and
may work for you now... give it a whirl.
