I don't know if the problem is fixed in -current, but I would upgrade
your boxes to at least 1.6STABLE to make it easier to try to deal with
the problem -- developers are for the most part not running 1.5.2
boxes.

Is it possible for you to bring any of the machines down to ddb and
poke around the system state, or to take a kernel core dump and look
at what the state of the console device stuff is? Also, what
architecture are you running?
