[ath10k][QCA9377] Firmware crashes on Dell Inspiron 5567 (IRQ #16, all modern distro kernels)
Hello,
This is to inform all that constant firmware crashes have been seen in the "Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter", which was shipped with the Dell Inspiron 5567 laptops. This affects every kernel release, including the stable and the longterm ones.
All the logs have been taken after livebooting an Arch Linux ISO.
Every distro has been tried, and it has been confirmed that some error of this kind is shown in every distro.
## Steps to reproduce the issue
1. Boot/liveboot any Linux ISO through this card (and possibly, this laptop). 2. Wi-Fi network interface appears. 3. Connect the Wi-Fi router to the computer. 4. A few moments/minutes after that, the touchpad stops working, and the network interface cannot even access the Internet anymore (BUT, the network interface might disappear, might not disappear).
## Affected distros and the necessary workarounds
This has been the pattern on every distro and their corresponding kernels (LMDE, Linux Mint, Pop!_OS, Zorin, Kubuntu, KDE Neon, elementaryOS, Fedora, and even Arch). The fix which made these distros usable is to add two things:
- Adding "options ath10k_core skip_otp=y" to a new conf file in /etc/modprobe.d. - Adding "pci=noaer" in GRUB kernel parameters so that the logs are not flooded with Multiple Correctable Errors.
To defend my case (that it occurs in the other models of Inspiron 5567 too), I have recently contacted someone running Linux Mint on the same model. The answer was the same: the touchpad and the Wi-Fi stop simultaneously.
## Some of the limitations
The kernel was tainted, but the other things have been properly noted in case they might provide some useful details. As stated, investigating why IRQ #16 is disabled will probably give us the answer.
## Logs provided
All the logs in a combined manner can be found here: https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180
- Full dmesg: https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180#fil... - Hostnamectl: https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180#fil... - lspci: https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180#fil... - Modinfo of the driver: https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180#fil... - Ping command: https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180#fil... - /proc/interrupts: https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180#fil... - IP addr command (Heavily Redacted): https://gist.github.com/BandhanPramanik/ddb0cb23eca03ca2ea43a1d832a16180#fil...
Lastly, this issue on the GitHub repository of Pop!_OS 'might' be relevant: https://github.com/pop-os/pop/issues/1470
It would be highly appreciated if the matter were looked into.
Thanks,

Hello,
An update on the situation.
I installed Fedora KDE Plasma Spin, and the skip_otp option didn't work there. KDE specifically said that the Wi-Fi is still connected but it is not connecting to the Internet (confirming my suspicions as true, that the network interface is not disappearing this time and the Destination Host is unreachable, because of the network card).
Only the following convoluted (and strictly step-by-step) solution seems to potentially work (not tested on my own laptop yet): https://www.reddit.com/r/linux/s/8VKDJ6QeP (This solution has been taken from the GitHub Issue of the Pop!_OS repo)
I used these exact sequence of steps before, and it worked properly. But this time, I simply wrote the skip_otp option to /etc/modprobe.d, and it didn't work.
Reiterating my point: this issue seriously requires urgent attention because it affects all the stable and longterm kernels as of now.
Thanks,
Bandhan Pramanik

For some reason, the Reddit link on troubleshooting the firmware leads to nowhere.
Here is the Reddit link yet again (let's see if it works): https://www.reddit.com/r/linux/s/egXvRBYhYp
Apologies for interrupting more than once.

Resending this as it appears that the original message did not reach the ath10k mailing list.
