Seen in the dmesg for next-20130325, but looks like it's been doing
it since at least next-20130218.

'git blame' doesn't seem to shout anything. Commit 112202d90 touched code
in that area semi-recently, but I don't actually see a problem with it.
(I admit not being sure how long this has been an issue - discovered I
had a local config screw-up that meant lockdep wasn't on for quite some
time).
