Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

Are you using IBSS?

Yes, I have an IBSS access point defined in wpa_supplicant.conf for my Nokia N9.

...

Adding "frequency" parameter was the missing piece getting mobile tethering to work at all. That's probably unrelated to this particular bug, though.

Can you run run tracing?
I'd need to see what happens here...

Also - can you try on latest and greatest?
You can use backport if needed

Is "with tracing" the same as "can you please try to reproduce with debug=0xf ?" above?

"Latest and greatest" means 3.13-rcX iwlwifi?

In , emmanuel.grumbach (emmanuel.grumbach-linux-kernel-bugs) wrote :

latest and greatest means wireless-testing tree - or backport.

tracing means running trace-cmd and making sure that tracing for iwlwifi is enabled.
I can help if needed

I'm seeing this exact bug with my notebook.

$ uname -a
Linux arch 3.13.6-1-ARCH #1 SMP PREEMPT Sun Mar 16 02:34:26 CET 2014 x86_64 GNU/Linux

Can I provide any useful info?
I already activated iwlwifi-debugging and will attach a log from around the time of the error.
It occured on "Mar 17 22:43:43"

This bug is a FW bug and won't be fixed. Since the recovery flow kicks in and works well, I consider this bug as closed.
