We have seen three 3b1's with this problem.  One of them had it
from the day it was delivered by AT&T, the others "developed" it
after the motherboards were replaced for other reasons.

I seems that AT&T is not checking the motherboards out very well
after they replace them.  All of these machines would pass 
diagnostics; none of them could print properly.  We have also
had problems with "new" motherboards having bad serial ports.
In both instances, the port could send data but would not receive
any data.

Don's assume that the replacement motherboard is any better than
the one you took out.
