In fact, I found a reproducible way to lock up the system: 1. Turn off WiFi 2. Reboot system 3. Login 4. Turn on WiFi If you perform those steps, the system will lock on ath11k-qca6390-bringup, dmesg: https://i.imgur.com/0XExack.jpg On 59c6d02 + revert of 7fef431be9c9, the firmware will crash but the system will not lock up. dmesg: https://pastebin.com/raw/hH0HyWVx If you keep WiFi on, i.e. the system is automatically connected to WiFi on boot, then on the ath11k-qca6390-bringup tag, it randomly freezes. On 59c6d02, it seems to be fairly stable so long as I do not turn off/turn on WiFi. I can bisect based on the reproducible steps in the next couple days if nobody else comes up with something first.
