Subject: Badness at net/ipv4/inet_connection_sock.c:293

Hi there,

today I upgraded from 2.6.32-rc7 to the latest -git (mainline) and after a 
few hours the messages below appeared in the log. Apparently "privoxy" was 
very busy handling connections, but the messages never appeared with 
earlier kernels. 

Full dmesg & .config is on:
http://nerdbynature.de/bits/2.6.33-git/inet_accept/

Thanks,
Christian.
