I think, there are also other manufacturers, who have problems with
their UARTs.

  - The first version of 16550 should not have been used with its FIFO.

  - The SCC-2692 datasheets tells something about lost characters under
    certain circumstances (reads horrible, but seems to work in praxi).

So there might exist other UARTs with problem, but you simply don't know
it and therefor your happy.
It's good, that Microchip reports the bugs.
