dmesg | grep Bluetooth

I'm on arch Linux. For a while now (multiple kernel versions since 5.15 at
least) my qca firwmare seems to crash. Weirdly bluetooth stops working and WiFi
still works fine.
There is nothing in particular that seems to trigger this. I just have to wait
for a while. Sometimes a few minutes after boot sometimes a few hours. 

Rebooting without a power connection or booting into Windows usually resolves
this issue.

I'm on a 2020 Dell XPS 9500. Fimrware is up to date at 1.13.

Output of uname -a: Linux kai-xps 5.17.3-arch1-1 #1 SMP PREEMPT Thu, 14 Apr
