This looks like a known problem in find_candidate that's fixed in
2.0.31-pre9. I would recommend that you upgrade your kernel.

Hi Bill - I had been running 2.0.31-pre9, but backed down because
of two networking bugs in -pre9 that make it undesirable to use.
I posted a note to linux-net@vger, but there were no replies/followups.
(Maybe I should have copied Andi Kleen?)

The first problem is that when 2.0.31-pre9 communicates with windoze95
(mgetty/pppd-->modems<--win95/dialup-networking), packet throughput is
erratic, especially uploading to linux from win95, running about 50%
of normal. Packets will flow at full speed for 1-2 seconds (2-3
packets, 3-5KB), then freeze for 1-2 seconds until a retransmission
gets things going again. Backing down to 2.0.30 fixes this problem
completely.

The second problem is that opening a connection with 2.0.31-pre9
results in `connection reset by peer' some small percentage of the
time; backing down to 2.0.30 reduces the incidence rate to about half
(though this is a very subjective interpretation). It also affects
IP-forwarding as with win95 above.

So for me, I'll have to either back down to 2.0.29, else wait for a
more stable network in 2.0.31-pre10?
