Need to compile with CONFIG_IWLWIFI_DEBUG enabled
Comment 6 Emmanuel Grumbach 2013-09-11 05:14:10 UTC
but yeah - other than that the config file looks good.

I'm seeing iwlwifi problems after resuming from suspend. Here's an example of a recent encounter of bug topic signature. Heuristic estimations put the problems starting somewhere after 3.10.10 releases.

This is where I notice endless fail loop and just force unload the modules.

Are you using IBSS?
Comment 10 Leho Kraav 2013-12-18 09:12:58 UTC
Yes, I have an IBSS access point defined in wpa_supplicant.conf for my Nokia N9.
Comment 11 Leho Kraav 2013-12-18 09:15:45 UTC
...

network={
    ssid="Nokia_10F9EEF6A044"
    key_mgmt=NONE
    auth_alg=OPEN
    mode=1
    frequency=2412
}

...

Adding "frequency" parameter was the missing piece getting mobile tethering to work at all. That's probably unrelated to this particular bug, though.
Comment 12 Emmanuel Grumbach 2013-12-18 09:16:14 UTC
can you please share your wpa_supplicant.conf?
Comment 13 Emmanuel Grumbach 2013-12-18 09:16:30 UTC
argh - race :)
Comment 14 Emmanuel Grumbach 2013-12-18 09:19:11 UTC
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
Comment 15 Leho Kraav 2013-12-18 09:22:30 UTC
Is "with tracing" the same as "can you please try to reproduce with debug=0xf ?" above?

"Latest and greatest" means 3.13-rcX iwlwifi?
Comment 16 Emmanuel Grumbach 2013-12-18 09:24:09 UTC
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

journal-log of the error

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"
Comment 18 Emmanuel Grumbach 2014-03-18 06:13:35 UTC
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.
