Serial board with 16550's

[Gary Grebus]

Can anyone recommend a vanilla two-port serial/printer card that is
known to work with NS16550's installed?  I realize many of these are
"unbrand" clones, but any pointers would be
helpful.   The board I currently have works fine with the original
16450's  but hangs frequently
with the 16550's (this is using FAS 2.07 to drive it).

Thanks.
