AX210 Bluetooth does not work on a warm reboot #674

Open Joshua-Riek opened 6 months ago

Joshua-Riek commented 6 months ago

@nyanmisaka found that the USB Bluetooth for AX210 only works on a cold boot. When entering the command sudo restart, the Bluetooth USB disappears. This has been observed on the 5.10 and 6.1 Rockchp kernels and multiple RK3588 devices.

The difference that can be noticed is that the following is added to the working dmesg log. rfkill enables usb bluetooth (0x8087 intel bt).

This issue is not specific to rockchip kernel, but to ubuntu-rockchip. I built armbian from scratch and found that it was not affected.

Interesting. I will need to do some digging.
