In this case the laptop just resumed from hybrid-sleep but this also happens on a freshly booted Linux.
The hardware in use is a MacBook Air 6,2 with

maximilian@kaul_mba ~ $ lspci | grep Wireless
15:03:00.0 Network controller: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter (rev 03)

The driver is

maximilian@kaul_mba ~ $ pacman -Qs broadcom
local/broadcom-wl-dkms 6.30.223.248-1
maximilian@kaul_mba ~ $ uname -r
3.16.3-1-ARCH

The effect I get (besides from a full journal) is frequently losing and regaining network connectivity (intervals < 1 min).

What do I do with this? Is this something to report to the arch or even kernel bug tracker?
Does anyone else experience the same issue? Is there a known workaround?

Thank you for your help

Re: cfg80211 kernel warning

I switched to the non-dkms broadcom driver by now and believe that the problem occurs less often by now.
But just as I read your post my wifi decided to act up again and here is some dmesg output

No good here.

# lsmod | grep bcma

doesn't return anything. As far as I understand it rmmod will do nothing if the module isn't loaded (and therefore shows up in lsmod).

Re: cfg80211 kernel warning

I have been seeing this on my Thinkpad with and intel wireless card.  So I don't think that it is specific to broadcom kernel modules.

What I have noticed is that for me it seems as though the issue occurs when my machine suspends or resumes.  So I tested to see if removing the iwlwifi kernel module would help.  This seems to kind of help, but I still would like to figure out what is actually going wrong here.

Re: cfg80211 kernel warning

look the sme.c in linux 3.15 (works broadcom bcm43142)  http://lxr.free-electrons.com/source/ne … e.c?v=3.15
and this is sme now:  http://lxr.free-electrons.com/source/net/wireless/sme.c
this has one change , wiphy_to_dev() to wiphy_to_rdev()
but that's not for me ..
