Hmm, interesting I hadn't received such reports yet..
I am afraid this was caused by a patch which was send to 2.6.26 to fix a lockdep problem. :(

John, earlier today I released the patch:
rt2x00: Use ieee80211_hw->workqueue again
http://article.gmane.org/gmane.linux.kernel.wireless.general/17305
actually intended for 2.6.27, but if this bug means 2.6.26 might be crashing, it might
be wiser to push it to 2.6.26.

it only very recently showed up on kerneloops.org (the .9 release from Fedora is only a 2 or 3 days old).
In addition, while I monitor what's going on, oops patterns need to cross roughly a 25/week pattern for
me to notice them as standing out...

If I see other patterns come up I'll send out email again ;-)
