IOW, is the problem machine doing lots of receive or lots of transmit?

Neither uploads nor downloads work in interrupt mode. Both work in
polled mode.

Ho hum. This probably requires the use of a serial splitter so that
an independent known good machine can monitor what's being sent by
each end.

Since you have 2 serial ports, can you test
using ttyS1 as the console (kernel boot parameter console=ttyS1)
and do a transfer on ttyS0 (interrupt mode) with a separate
connection to another machine?

This at least removes interaction with the console
from the picture.
