This is very weird, because TFO is TCP and the DNS queries fired off by polipo are UDP: root@OpenWrt:/tmp/log# tcpdump -n -v -vv -vvv -x -X -s 1500 -i lo

This is the only DNS traffic I saw during the attempts. The tcpdumps have udp bad checksum but when I disabled TFO in polipo, the UDP where still bad checksum but they worked. Really weird.
I think this is a side effect of the loopback interface not processing checksums by default. I will be more worried if the checksum errors also occur on ge00, but am not ruling out problems with the unaligned access patches yet.
As an aside, I've noticed very occasional issues connecting to (IPv4-only) sites using both Sugarland and the 3.6.10 release, which gets fixed when the connection is retried. I have been unable to repeat this on demand, however.
