I am seeing this error on shutdown with 3.10 and net-next (on Debian 7.0) Looks like a problem with lockdep seeing issues with canceling work in ixgbe with rtnl held?
Not a bit issue, shutdown still works and no real big issue. [ 310.416382] INFO: trying to register non-static key. [ 310.417499] the code is fine but needs lockdep annotation.
