Since you're not using the UHCI controller on that computer, you could
simply rmmod uhci-hcd (or modify /etc/modprobe.conf to prevent it from
being loaded in the first place). That would stop the constant interrupts
and the syslog spamming.

For the syslog spamming, you could jus emit the message once when the
state is first noticed, then emit a everything good message when it
clears up. There's no need to log it repeatedly during the problem
period.
