After a kernel bisect, it was found that reverting the following commit resolved this bug: commit 716ec052d2280d511e10e90ad54a86f5b5d4dcc2 Author: Hong Zhiguo Date: Sat Sep 14 22:42:28 2013 +0800 bridge: fix NULL pointer deref of br_port_get_rcu The regression was introduced as of v3.12-rc2 and has made it into some of the stable trees(3.10 and 3.11). I was thinking of requesting a revert for this commit, but I wanted to get your feedback first, since you are the patch author. Thanks, Joe [0] http://pad.lv/1249880
