As I noted earlier this comes from the fact that a driver or mac80211
is queuing work onto the mac80211 workqueue when we already ran the
mac80211 suspend callbacks and we haven't yet resumed. There have been
several fixes for these, for both drivers and mac80211. We've already
pushed them to wireless-testing but I do not recall which ones have
been propagated to 2.6.31 as fixes.

So we have two options, we either treat all these as real issues for
2.6.31 and try to backport all related fixes, or we downgrade this
warning to just bail out. The problem with debugging these issues
as-is on 2.6.31 is that the caller which queued the work remains
invisible to the trace from the warning -- the warning comes from the
workqueue callback not the routine which ran queue_work(). This was
recently changed in wireless-testing and we now issue the warnings
from the callers of queue_work() for the mac80211 workqueue so we
*can* easily see the root cause to the issue and easily fix this.

We can surely fix this issue alone but we're sure bound to see this
warning later from other buggy drivers/mac80211 on 2.6.31 so we do
need to address how we want to address this issue as a whole for
2.6.31.

Fabio to help iron out this issue can you please use wireless-testing,
use IBSS as you were and go through the suspend-resume cycle to see if
you see a new warning with ath5k.

This one sounds like an IRQ routing error, so probably ACPI, but we've
been totally unsuccessful at getting any further information out of the
submitter. Use your own time judgement on this, but if he hasn't been
responding to you either for 36 days, I'd suggest closing this as
unresponsive.

This is on my todo and I haven't looked into this very hard yet,
but afaik ath5k doesn't (directly) use the mac80211 workqueue, so
my guess in Fabio's case would be further up the stack.
