Interesting...I've also had problems getting 16550's to work, and the
chips were the WD version.
I had the same experience as Bill with the Esix asy driver.  I don't
believe FAS worked either.
The symptoms were a hung port.  Poking around with crash led me to
believe a xmit done
interrupt had gotten lost.  At the time I wrote it off to bugs in the
el-cheapo serial card.
Anyone else seen problems with the WD 16550's.
