This message came from a BUG_ON statement in __netif_schedule(). A subsequent
commit changed it to a WARN_ON, and finally commit 5b3ab1d removed it completely
as the tested condition was essentially harmless.
You should be aware that wireless has not worked since commit
175f9c1bba9b825d22b142. See the thread at
http://www.ussg.iu.edu/hypermail/linux/kernel/0807.3/0936.html for details. This
problem is not yet formally entered at bugzilla as a regression.

Actually wireless is *partially* working for me. It seems that there's
a lot of packet loss though.

Ignore this, I'm no longer getting this oops on the latest git tree.
