bt-adapter is consistently crashing after disabling Bluetooth using rfkill. This was originally reported in Fedora by multiple users.

I'm getting this now. bluetooth not working and this is what I see when I run bt-device -l

Same here, after updating to latest kernel

[vdegenne]

Same here, and when that happens I usually can't active or deactivate the bluetooth from the gnome desktop settings GUI.

Had the same issue suddenly appearing during runtime on Linux Mint 19.3, although bluetooth had been working before without issues (I have my mouse connected via Bluetooth, thus I realized the issue right away).
I could not find any hints in the kernel logs and neither restarting the bluetooth kernel module, nor rebooting the system helped.

But one thing "fixed" it: shutting down the system completely, unplugging from power source, waiting for a minute and then replugging and booting again. Strange...

I'm getting this issue too

For some reason this "fixed" it for me too... Likely some kind of interaction with power options or USB autosuspend or something?
I'm archlinux on an Z590 Taichi, using the Killer AX1675x.
