Subject: Linux 3.4.83 update: wireless card (iwlwifi) stop working
Hi,
I updated today to 3.4.83 kernel and my wireless card stop working (log
says: iwlwifi 0000:03:00.0: Unable to initialize device).
My laptop is a Lenovo Thinkpad X230, with an Intel 6205 AGN card.
Reverting patch
Johannes Berg <johannes.berg@...el.com>
iwlwifi: always copy first 16 bytes of commands
makes it work again.
Regards,
Andres Bertens
