Subject: Wireless regression in workqueue: use mod_delayed_work() instead of
__cancel + queue
My Intel 6250 wireless card (iwldvm) can no longer associate with a
WPA-Enterprise network (PEAP-MSCHAPv2). To my surprise, I bisected this
regression to commit e7c2f967445dd2041f0f8e3179cca22bb8bb7f79,
workqueue: use mod_delayed_work() instead of __cancel + queue.
A bunch of logs collected by Ubuntu apport are in this bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1083980
How can I help to debug this?
I see that someone else reported another regression with the same commit
last week, although this looks unrelated at first glance:
