Description Justin Dray 2015-08-20 11:23:10 UTC
In the latest RC (Haven't tested previous RC's for 4.2.0) my Broadcom BCM43602 (MacbookPro11,4 - mid-2015 15")  takes 60 seconds after boot to show up in `ip link`.

At the same time I get this message in the journal:
Aug 20 21:10:05 justinmacbook kernel: brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Mar 13 2015 08:11:08 version 7.35.177.36 (r540934) FWID 01-e4dc1
Aug 20 21:10:05 justinmacbook kernel: brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code

After this the wireless device mostly works fine, but I haven't had a lot of time to test it at length. This regression is easily repeatable on the latest mainline.
Comment 1 Anthony Brice 2015-08-23 05:10:23 UTC
I can confirm the issue affects the MBPr 12,1 as well.
Comment 2 Justin Dray 2015-08-24 06:56:41 UTC
I've also noticed that when going to suspend/hibernate that exactly 60 seconds after resume the whole system will lock up if brcmfmac is loaded. Not sure if this is related or not. Manually running rmmod brmcfmac before suspend, then modprobe brcmfmac afterwards results in me being able to see wireless networks but oddly enough not my own one via network manager. using wifi-menu/netctl I was however able to see and connect to my network.
Comment 3 Justin Dray 2015-08-24 07:01:02 UTC
Sorry for double post. When restarting networkmanager it spews out the following kernel trace (again, this is only post-resume from hibernate/suspend):

Comment 4 Adrian Bjugård 2015-09-02 11:57:39 UTC
Also 5 GHz doesn't work, and the correct physical MAC address isn't recognised properly, everyone with this card (14e4:43ba) gets assigned the MAC address 00:90:4c:0d:f4:3e. Even by spoofing MAC address, it isn't possible to have two users of this card in the vicinity of each other.
Comment 5 Arend van Spriel 2015-09-05 13:15:05 UTC
This issue has been root caused as a firmware issue. We are preparing a new firmware release to linux-firmware repo.

This is regarding the 5GHz operation and mac address issue.

The 60 seconds suggest firmware loading using some timeout. Do you have the brcmfmac driver built-in the kernel or using it as a kernel module?
Comment 8 Justin Dray 2015-09-21 18:27:04 UTC
It is a module.

I had the 60s to load problem when I was compiling the linux-mainline package on ArchLinux, I think it only happens when the kernel is running with debug enabled? I'm not getting it with the linux 4.2.0-4 package from the testing repo, and I wasn't getting it with 4.1.6 from core either.
Comment 10 Anthony Brice 2015-09-21 19:12:39 UTC
Prompted by Adrian's comment, I enabled Arch's testing repositories and enabled its kernel. I can confirm that fixed the 60s to load problem on my machine.
Comment 11 Justin Dray 2015-09-22 08:41:35 UTC
I can also confirm the testing 4.2.0-4 kernel in arch's testing repo fixes the 60s to load issue. The MAC address is still forced to 00:90:4c:0d:f4:3e however. And I do not appear to be able to see or connect to 5GHz networks still. But they existed in 4.1.x as well; so the regression is fixed? but networking is still fairly broken.
Comment 12 Arend van Spriel 2015-10-08 07:33:21 UTC
Please try latest firmware in linux-firmware repository [1].

Arend

Running 4.4.2 on Dell XPS 13 (2016) with latest brcmfmac4350-pcie.bin from linux-firmware repo and I get the timeout still:

Is there an updated firmware for this chipset?
Comment 15 hoxnox 2016-03-02 18:34:27 UTC
Almost the same for me with Dell XPS-15 9550 (2015)
It has Dell Wireless 1830 WiFi, which is bcm43602-pcie  (attached lspci -vvnn).

I'm able to connect to my 5GHz network (TP-Link Archer C7), but after some time (5-7 seconds) connection is lost.

I'm having the same issue with my last dell xps 13 (2016) laptop since last update...
How can I do?
Comment 18 Niels Dettenbach 2016-06-02 10:49:25 UTC
Have the same 60s problem (on MacBookPro 11,5).

Same after suspend (hibernate to ram).

I tried the firmware blob as described here plus from linux-firmware (git), but that crashes instantly the kernel (could not debug it further att) when try to load. I'm on Gentoo (with gentoo kernel patchset) and not know if the guys here have modified something related.

best regards,

Niels.

I also touched this problem in Dell XPS-13, with Fedora 24 system.

I also have archlinux on Dell XPS 13' 9350 and have a similar problem. lspci and dmesg outputs are pretty similar to Pewho's.
Comment 24 lbrito 2016-10-04 15:31:28 UTC
Same issue here. Dell XPS 13 9350 with Broadcom Corporation BCM4350 802.11ac Wireless Network Adapter [14e4:43a3] (rev 08).

I'm using Ubuntu 16.04 with the 4.8 kernel. brcmfmac errors are logged in dmesg every 60s or so:

[  449.586402] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)
[  517.154683] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)

[  650.273411] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)

And when the error happens, wifi dies for ~10s. This issue did not happen with me when using kernel 4.7.

I also experience this issue on a MacbookPro 12,1.

Just an update:
I'm on a new kernel 4.8.1 with linux-firmware 20160628 (Gentoo) with no change. After loading the brcmfmac module it takes a minute until upcoming with the network device. Same happens when rmmod and insmod the module again. Seems it run's into any timeout while firmware loading or similiar.

I've reported this bug on Launchpad, please subscribe so that the bug can get some traction and we can work towards a solution: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1630324
Comment 29 Orion Poplawski 2016-10-17 14:52:40 UTC
To avoid the minute delay in loading the module, make sure that CONFIG_FW_LOADER_USER_HELPER_FALLBACK is not set in the kernel configuration.  New elrepo kernels should have this.  See http://elrepo.org/bugs/view.php?id=671.

I ended up swapping the wireless card for an Intel one.  Easy and works great.
Comment 30 hoxnox 2016-11-10 19:25:50 UTC
I've flashed my router (Archer C7 v2) with dd-wrt (ftp://ftp.dd-wrt.com/betas/2016/11-01-2016-r30826/tplink_archer-c7-v2/), configured 5Gz network as follows:

Wireless Mode: AP
Wireless Network Mode: AC/N-Mixed
Channel Width: Full (20 MHz)
Wireless Channel: 40-5200 MHz

The connection is fast and stable, but I still getting error about ISO code.
Comment 31 Christophe de Dinechin 2016-12-21 11:11:23 UTC
I see a systematic driver crash on a Mac Book Pro 15" running Fedora 25 Workstation, following the same "not an ISO3166 code" message.

It only happens when connected to one of my two base stations, a Freebox Revolution. As far as I can tell, 5GHz is not enabled on that base station (the configuration page says it's using a 40MHz bandwidth at 2.4GHz, channels 12 and 8). It happens every time I enter a Wi-Fi password. From a user perspective, it looks as if the Wi-Fi password was bad, there is no notification other than in dmesg.

The other base station is an old  Airport Time Capsule, and there is no issue connecting to it.

The stack trace is:

Comment 32 archenroot 2017-01-05 07:33:43 UTC
While being on 4.8.6 gentoo kernel, kernel got panic while connecting to WPA2-PSK only network, when connected with no security network, newer experienced this behaviour.

I just upgraded to 4.9.0 and will check the situation again.

Output of dmesg after first boot:

I am on package sys-kernel/linux-firmware-20160331.

After this refresh I can confirm that I can now even connect to WPA2-PSK network which didn't work on older kernel and older linux-firmware package although the firmware version looks like not updated.

I still see in new kernel some weird stuff in dmesg output:

But so far I stable for 1 hour, usually the kernel panic happened when I used some heavy parallel downloading/uploading, so I will do some stress testing.

Well, it looks still the same, not sure how I got it working, but I cannot connect to WPA-PSK netowrks again.

Problem apparently goes away for me after upgrading to 4.9.

It doesn't for me, I use kernel 4.9.3-200 on Fedora 25 workstation (macbook pro mid-2015)
