Hello,
I'm facing a new issue after upgrading from 3.1 to 3.2.
It happens when switching on/off my wireless card (BCM4313 [14e4:4727]).
Here's the oops I'm getting:

Hi all,
I'm wondering now why the brmsmac driver had been removed from the
staging driver tree if no one cares.
Bye.

What kernel tree are you using?

After this warning I can't connect to an AP anymore, I have to unload
and reload the brcmsmac module.
Thanks for your time.

Sorry for the delay in getting back to you. Still care about our
brcmsmac driver, but I can only work one issue at a time.

Did this problem occur with plain 3.2 kernel. I checked out the v3.2
mainline tag and looked at line 2979:ieee80211_rx():
2975: /*
2976: * The same happens when we're not even started,
2977: * but that's worth a warning.
2978: */
2979: if (WARN_ON(!local->started))
2980: goto drop;

I guess brcmsmac is sending up a received wireless packet to mac80211
and it is dropped, because mac80211 did not yet call the start callback.
It is just a warning so if you are having problems connecting to an AP
you may have other issues. As the comment states it is worth a warning
so I will look further into this.

Mainline but I added one patch which allows me to use the bcrmsmac
driver while bcma is enabled.

I forgot to ask. With switching on/off you mean the RFKILL switch?

Hi Francis,

People do care, it's just that time is limited, and people are busy.
Whilst nobody has provided this advice, the usual "My device doesn't
work and I'm not using the latest version of the driver" / "My device
doesn't work and I'm using my own patches" advice is to use the
bleeding edge Compat Wireless, without any extra patches, and see if
the problem can be reproduced with that.
See here:
http://linuxwireless.org/en/users/Download
Compat Wireless is the current wireless stack re-packaged to be
compilable on older kernels. Give it a shot, tell us if it works.
Thanks,
