There are two different applications reporting
problems in this one thread.

Lee's friend is the only one using MIDI,
Raphael is having problems with regular
serial communications.

Both are receive problems that started
with the 2.6 series, but may or may not be
the same problem. Lee is reporting lost data
and Raphael is reporting rx overruns.

I asked Lee to clarify which driver his friend is
using (the MIDI 16550 or standard serial 8250).
His original post stated "a serial MIDI card (supported
by the bog standard 8250 serial driver)".
