ath10k_pci QCA6174 firmware crash on suspend

[Yvan Masson]

Hi,

Another issue with Qualcomm Atheros QCA6174 (very similar to https://bugs.launchpad.net/ubuntu/+bug/1827879), this time using Mint 20.1/Ubuntu 20.04: when suspending laptop, firmware often (80%) crashes (see kernel log at bottom). It prevents the computer from properly suspend, and many component hang (can't poweroff properly, can't use "sudo", can't "modprobe -r" or "rmmod"…), so it basically makes the computer unusable once this happens.

If I manually unload ath10k_pci module before suspend, suspend/resume works perfectly. Unfortunately, I could not find a reliable way to unload this module before suspend (either via a systemd unit or via /lib/systemd/system-sleep/ script).

If I understand properly, the issue comes from the loaded firmware (/lib/firmware/ath10k/QCA6142/hw2.1/firmware-5.bin) which is proprietary so can't be fixed. However, fixing the ath10k module or the kernel so that it can recover from such a problem would be great if possible. Note that I tried with linux-image-generic (linux-headers-5.4.0-74-generic) and linux-image-generic-hwe-20.04 (linux-image-5.8.0-55-generic). Package linux-firmware is in version 1.187.14.

Regards,
Yvan

Same thing for me: Dell XPS 13 with QCA6174 wlan card
It often crashes after the laptop suspend

No porblem if I manually switch off the wlan before suspending.
