Yup. When the power flickers, they still function fine behind the UPS
(despite a 0.5 volt drop). I still have yet to determine the reason
for the lockups, despite a bit of testing.

 Thanks to all who contributed, this thread has been quite quite
helpful.  It looks like I have a bit of shopping around to do now.
I'll report back to the list if I find anything noteworthy.

Thanks guys!
