Lars Peter Thomsen, thank you for reporting this and helping make Ubuntu better.

In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results.

Thank you for your help.

[Patric (pakar)]

Issue is in 4.7.0 too.

Wifi *may* stay working for fairly long periods (2-3 hours) in some lucky instances.

Tests performed:
1. unload/load brcmfmac module.
   Result : Interface is stuck in "Link is not ready"

2. suspend system and resume.
   Result : Interface is stuck in "Link is not ready"

3. unload brcmfmac module and suspend. After resume manually load the module again.
   Result : Interface is stuck in "Link is not ready"

4. Warm reboot of the system.
   Result : Interface is stuck in "Link is not ready"

5. Full shutdown and cold-boot.
   Result : Interface comes up as expected and works for some time.

Have not been able to look into activating debug-output from brcmfmac (module debug-parameter) yet.

[Patric (pakar)]

Attached to this comment is a debug log (non-working-state_modprobe.txt) from the brcmfmac module while loading it but network-card failing to come up as it should.

Module loaded with:
$ cat /etc/modprobe.d/brcmfmac.conf
options brcmfmac debug=0xffffff roamoff=1

[Patric (pakar)]

Adding log (nonworking-rmmod.txt) from when unloading the module too...

[Patric (pakar)]

Will attempt to capture some more logs when the card is working and when goes into the problematic state.

[penalvch (penalvch)]

ldc, to capture your hardware, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

[penalvch (penalvch)]

Lars Peter Thomsen, to keep this relevant to upstream, please continue to test the latest mainline kernel as they are released (now 4.8-rc3). Could you please advise?

[penalvch (penalvch)]

Lars Peter Thomsen, to clarify, did this issue not occur in a release prior to 16.04?

[Arnau Villoslada (thedegree0)]

I'm experiencing exactly the same problem on a XPS 15.

Christopher M. Penalver, this issue is present on 16.04.

[penalvch (penalvch)]

[Lars Peter Thomsen (lapeth)]

As I recall, the issue did not appear on 15.10

I updated to 16.10, and this issue now renders the system unbootable.

[penalvch (penalvch)]

Lars Peter Thomsen, could you please advise to the results of the latest upstream kernel 4.8.1?

[Lars Peter Thomsen (lapeth)]

Issue remains on 4.8.1. Boot is aborted and displays a rescue prompt.

I'll try going back to 15.10 and see if any kernel versions exhibit the problem. Are we sure that this is an issue with the kernel and not another package?

[penalvch (penalvch)]

Lars Peter Thomsen, could you please boot with 4.9-rc1 and provide the missing information from https://wiki.ubuntu.com/DebuggingSystemCrash ?

[Lars Peter Thomsen (lapeth)]

Reinstalling 16.10 from scratch has resolved the issue; I no longer see the issue with 4.9-rc1 or any other kernel down to 4.5.4. No clue why.

[Lars Peter Thomsen (lapeth)]

ldc (pakar) reports in post #5 that the interface may only stay up for a limited time. I'll report if I see the same behavior.

[Rohin Gopalakrishnan (rohinrohin)]

I'm facing the same issue on my XPS 15, Kernel 4.9LTS. Any updates/fixes for this?

[archenroot (archenroot-gmail)]

I had similar issue on Dell XPS 15 with:
02:00.0 Network controller: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC (rev 01)
 Subsystem: Dell BCM43602 802.11ac Wireless LAN SoC
 Kernel driver in use: brcmfmac
 Kernel modules: brcmfmac

I resolved this by loading the proper firmware into kernel. I am using Refind with support of UEFI bios, so my kernel is self loaded (no Grub or Lilo, etc.) including the firmware for specific hardware.

Here are some hints how I resolved non-working wifi. The .txt file is not available for some of brfmac devices (as my case as well).

Look here for detailed analysis and resolution, be patient as was also resolving how to properly load the firmware into kernel:
https://forums.gentoo.org/viewtopic-t-1060038.html?sid=0c86112016dd3a3410cd6a1fe9fe27d1

[Kai-Heng Feng (kaihengfeng)]

Do you mean that the wifi works if kernel is EFIStub, it doesn't work otherwise?

Or just put the wifi firmware into initramfs?

[archenroot (archenroot-gmail)]

Ok, well in my case I was:
- 1. missing the firmware at all as I thought it is not required for this device, but this was quickly resolved, my kernel config is as follows:
ares ~ # grep -Hrn "FIRMWARE" /usr/src/linux/.config
/usr/src/linux/.config:1541:CONFIG_PREVENT_FIRMWARE_BUILD=y
/usr/src/linux/.config:1543:CONFIG_FIRMWARE_IN_KERNEL=y
/usr/src/linux/.config:1544:CONFIG_EXTRA_FIRMWARE="brcm/brcmfmac43602-pcie.bin brcm/BCM-0a5c-6410.hcd"
/usr/src/linux/.config:1545:CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
/usr/src/linux/.config:3222:# CONFIG_CYPRESS_FIRMWARE is not set

/usr/src/linux/.config:3428:CONFIG_FIRMWARE_EDID=y
/usr/src/linux/.config:5000:CONFIG_FIRMWARE_MEMMAP=y
/usr/src/linux/.config:5009:# CONFIG_GOOGLE_FIRMWARE is not set
/usr/src/linux/.config:5408:CONFIG_TEST_FIRMWARE=y

2. The message "Direct firmware load for brcm/brcmfmac43602-pcie.txt failed with error -2" is not an issue in general, such file is related to calibration as per my understanding and is not provided for this device.

3. The message "brcmf_cfg80211_reg_notifier: not a ISO3166 code" might cause or not some issue, but this is probably related to manufacturer based on discussions on Gentoo forum

4. I got confirmation from one Gentoo guy from link referenced in previous post by me that he has the device and it works, but mine still didn't work. The last step I check was network stack app boot and found that both packages are in default runlevel:
net-misc/networkmanager-1.6.2_pre
net-misc/dhcpcd-6.11.3

Once I disabled dhcpcd (which is anyway auto-started on demand by NetworkManager and that was somehow causing issue and continuous switching of MAC addresses as well) I was able to connect to wifi.

Stability - I am on 4.10.3-gentoo kernel and:
A. At work/airports - I am on Open or WPA2-PSK secured network and all is fine, I didn't experienced disconnect or Kernel Panic for about 2 weeks
B. At home - Well, this is still strange. When I work alone all is stable, but when my wife sit at me and connect from here Android based Lenovo phone, in about less then ~5-30 minutes I get kernel panic. I will try to capture some more details about this strange and probably unique situation as I don't experience it anywhere else. (probably it is because of my wife :-) )

[archenroot (archenroot-gmail)]

Also I found out on raspberry forum, that this could be related to some specific channels which the AP is configured on:

[penalvch (penalvch)]

Lars Peter Thomsen, I am closing this report because as per https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1600624/comments/19 the bug has been fixed via installing a later release of Ubuntu.
