Async support in the original Dec 88 release never worked correctly, and was
essentially unusable in my config (buffered 4 port card, one at 19.2 SLIP,
the other 3 attached to Telebits.)  Async support even under heavy input
load works fine in the Sep 88 release.

I'd applied, but never run, the patches to the Dec 88 release (1.3) claimed
to make async support work, mainly because I had a device driver which was
said to be customized for the Sep release.  Now that I have a newer version
of that driver, I built a kernel, almost salivating at the prospect of
lower-overhead async support.

The problem is that I'm still seeing input overrun conditions with
this patched async support at a frequency of 10-20 per minute when
incoming network traffic is heavy (I haven't yet seen what TB+ traffic
will be like), compared to no more than one or two per day (if that)
under the Sep 88 release.

This is a great disappointment.  What have been other people's experiences?
Should I be resigned to stepping back to the Sep 88 release yet again????
