If there is some doubt as to what UART you are using, you can try
this... force you UART to on act like a 16450. You should be able to do
this using setserial. This will disable the use of the FIFO buffers which
*may* be causing your problems if you have a 16550.
Alternatively, if there are some bugs in the code that determine the
UART type, I'll go looking into it and send the patches (if any) to the
serial developers. Hopefully I can get to that later today.
