This is quite a show-stopper for me... and > before trying to bisect 11Mbyte of patches... hm, from your log it appears that lockdep did not find anything, still the hang does trigger. it's /sbin/ifconfig and inet_ioctl() / dev_close() / rtl8169_down() that seems to be hanging. I've extracted the relevant backtrace below. I've Cc:-ed people who might have a better idea about what's going on.
