I installed the 5.0.0-15-generic kernel and removed iwlwifi from the /etc/modprobe.d/blacklist. The system was stable and ran very well for 4 or 5 hours. When I booted it (still generic kernel) this morning, it failed after about 20 minutes. I rebooted and teed journalctl for documentation. The failure occurred after only 4 or 5 minutes. I will attach the log from this crash. ** Attachment added: "generic kernel log during failure" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776443/+attachment/5265227/+files/dell-inspiron-iwlwifi-7265D-29-generic-kernel-failure -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1776443 Title: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck Status in linux package in Ubuntu: Confirmed Bug description: dell inspiron 15 3565 and intel 3165.

My laptop runs ubuntu studio 19.04, but studio stopped including the linux-generic package many releases ago. By the way, /lib/firmware/iwlwifi-7265D-29.ucode is the latest on this 19.04 disco system, dated 18 May 2018, so I have confirmed it as broken with at least two earlier ubuntu releases and very many kernels.

[Kernel-packages] [Bug 1776443] Re: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck
After upgrading to 19.04 disco, the system is still too unstable to be useful. The current kernel is 5.0.0-13-lowlatency (buildd@lcy01-amd64-020). I note the Intel driver has not changed after the upgrade from 18.10 cosmic, i.e. still iwlwifi-7265D-29.ucode, packaged within linux- firmware version 1.178. The details of the stack trace are different, but the outcome is the same (attached). The wifi connection is lost and kernel error messages spew out to the log. Stopping and restarting wifi makes no difference. The only "solution" is to shut down the system and reboot. Luckily I have a usb dongle that uses rtlwifi firmware, which works OK. ** Attachment added: "disco kernel log when intel driver hang is reported" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776443/+attachment/5261968/+files/bacchus-iwlwifi-hang-log-disco-2019-04-27 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1776443 Title: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck Status in linux package in Ubuntu: Confirmed Bug description: dell inspiron 15 3565 and intel 3165.

Thanks for your comment, Kai-Heng, but I did try the latest upstrem kernel at the weekend. Please refer to my post #8. Is there a good reason to try a kernel more recent than:- linux-image- unsigned-4.17.0-041700-lowlatency_4.17.0-041700.201806041953_amd64.deb ... along with its associated headers and modules packages?

It takes me an hour or so and I am rather busy at the moment, so I don't want to waste time just to "test" a few extra but irrelevant changes... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1776443 Title: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck Status in linux package in Ubuntu: Confirmed Bug description: dell inspiron 15 3565 and intel 3165.

[Kernel-packages] [Bug 1776443] Re: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck
I installed the latest upstream kernel, headers and modules. As far as I can tell, it suffers exactly the same failure as the latest released bionic lowlatency kernel. The stack ttrace seems very similar and the timeout message looks to be the same. My guess is still the intel iwlwifi version 29 firmware (although all the older versions which will load onto my 3165 wifi adapter have failed in similar but not identical ways).

[Kernel-packages] [Bug 1776443] Re: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck
Joseph... I also thought I had mentioned this a quite a new machine, so it doesn't have a lot of history. However, I had a similar wifi failure quite often with the latest 17.10 kernel before the upgrade to 18.04. I will look for a 17.10 log if you think it would be helpful, but I'm not sure I kept any. More importantly, and more hopefully, I will try to install an upstream kernel as you suggest. I am certain of two things: 1. I have tried every version of iwlwifi from 29 back to 17. I'm pretty sure the older firmware packages would not work with my hardware and kernel versions. 2. If I blacklist iwlwifi and use a dongle with Realtek wifi adapter, the problem does not occur. Although it is possible this is a kernel or driver bug, my guess is we are dealing with a firmware bug. The Intel support page for this driver says: "Having Wi-Fi and Bluetooth running at the same time is a challenge." I am sure you will let me know if I can collect any other useful information, either before the failure, or after. In the meantime, I will follow the instructions by marking this bug "confirmed". ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1776443 Title: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck Status in linux package in Ubuntu: Confirmed Bug description: dell inspiron 15 3565 and intel 3165.

I won't confuse the matter with details, but after I reproduced the problem (obviously) apport could not reach launchpad because the wifi adapter was out of action.

The same system runs stable and perfect with a USB dongle Realtek RTL8188CUS, but I have to blacklist iwlwifi in /etc/modprobe.d/modprobe.conf to prevent iwlwifi hanging all network activity while simply scanning and not connected to an AP. I've had similar problems with this system under 17.10, but it has become more reproducible under 18.04. I've back-levelled the driver as far as possible, but they all hang the network. Because version 29 firmware is the latest in the bionic repository, and also on the intel support web site, I won't confuse matters by reporting earlier ubuntu kernels or iwlwifi versions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776443/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
[Kernel-packages] [Bug 1776443] Re: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

I'm pretty sure the same hardware adapter and firmware is supporting bluetooth for my logitech mouse. ** Tags added: wifi ** Tags added: intel -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1776443 Title: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck Status in linux-firmware package in Ubuntu: New Bug description: dell inspiron 15 3565 and intel 3165.
