SubjectRe: Strange interrupt behaviour

I was definitely planning on trying... I'm trying to throw together a PPP
router on a 4MB 486SLC. But after hearing about interrupt latency
problems, memory fragmentation, and having some strange problems with ppp
2.3.5 myself [1], it makes me a bit wary. Of course, I'll try it
nonetheless and let this list know if I come across anything strange.

[1] acks seem to be making it out over the PPP link, but never making it
back to the other side. This seems to show up in 2.1.106-ac3, but not
in 2.0.31+qnx [2]. I haven't ruled out the possibility of the acks
being snarfed by asymmetric routing, and am still running tests...
[2] Yes, the QNX scheduler... I love it. I hope it'll get ported to 2.1
one of these days...
