This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

*** Bug 611816 has been marked as a duplicate of this bug. ***
Comment 5 John W. Linville 2010-07-16 13:45:41 EDT
This warning occurs when ieee80211_sta_timer executes with the following conditions:

local->quiescing == false
local->suspended == true
local->resuming == false

It isn't clear how this could happen, but it seems like a narrow window.  I wonder if this can be recreated?
Comment 6 Scott Dodson 2010-08-16 16:11:34 EDT

I've not seen this again since I first reported it.
Comment 7 John W. Linville 2010-11-22 11:01:39 EST
Closing on the basis of the last two comments -- please reopen if you see this again (especially if you can recreate it)!
