[Damien Lecan]

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.

** Description changed:

  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
