Hmm, were these messages close together in time, or now and then a message?

I seriously doubt the freeze and these messages are related. The uGuru
only uses 2 io ports todo all communication with the outside. So reading
the ports doesn't always get you the same register there is a sortoff
network protocol which you speak over the ports. These messages mean
that the uGuru failed to response within a reasonable time. Unfortunate
on some uGuru's this is quite normal. It seems the older the
Motherboard, the more often this happens (iow the buggier the uGuru
firmware).
