Could it be that DTR is dropped during attach of the device, which is being
detected by your terminal server which is then dropping the connection?  That
wouldn't explain why it doesn't come back eventually though (the open from
getty should re-raise dtr if nothing else).  Some terminal servers actually
respond to the state of the modem signal lines (like dtr, dcd, etc).  For
serial console machines, I'd disable that behavior if possible.
