What kernel?

This is probably a driver/mac80211 adding work into the mac80211
workqueue during the susend --> resume cycle. We recently changed the
warning to be moved onto the actual caller who does the queue_work()
so we don't have to guess at this and do a painful debugging.

I suspect you are not using the latest wireless-testing.
