I double-checked the warning, and indeed in the 3.0.23 tcp_input.c at
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=blob;f=net/ipv4/tcp_input.c;h=ee08f11ff21a802faa8b32efc1eb312e479878d6;hb=bf6a68d2a214e07f7c0d6538e00e17b826714160#l3375
that line is:
WARN_ON((int)tp->sacked_out < 0);
So this indeed looks like the known issue that is fixed by the commits
Eric mentions, which are in 3.0.25.
