I started seeing these messages spewed (to both console &
/var/log/messages) following an update from:

As far as I have been able to tell so far, the machine (my laptop) is
not exhibiting any (aother) indications of problems.
I confess that I am not entirely clear on what information the
message is apparently trying to convey (let alone what I can or
should do about it -- if anything).
Peace,
