I'm not familiar enough with the tcp code to know if this patch
(against -ac6) is a solution, band-aid, or, in fact, wrong, but
I've run with it (on -ac3) and haven't seen the errors for over
twelve hours, which is three times longer than it had been able to
go without it coming up.
See the fix I put in 2.4.1-pre2, which is:
diff -u --recursive --new-file v2.4.0/linux/net/ipv4/tcp.c linux/net/ipv4/tcp.c
--- v2.4.0/linux/net/ipv4/tcp.c Tue Nov 28 21:53:45 2000
+++ linux/net/ipv4/tcp.c Wed Jan 10 14:12:12 2001
