Title:
Bluetooth failure on reboot - Kernel 6.11.0-17 - Mediatek 7921
Status in linux-signed-hwe-6.11 package in Ubuntu:
Confirmed
Bug description:
Using kernel 6.11.0-17, Bluetooth works on first boot. If I reboot,
GUI settings shows Bluetooth Turned Off and the on/off slider is
completely inactive
Ubuntu 24.04.2 (fully upgraded)
Gnome 46 (Wayland)
GMKtec NucBox K2, AMD Ryzen™ 7 7735HS with Radeon™ Graphics × 16, Wifi
and bluetooth combined Mediatek mt7921
Bluetooth both first boot and reboot, performs flawlessly with Kernel
6.8.0-52 and earlier
I expected the Bluetooth adapter to be available upon a reboot with kernel
6.11.0-17
The Bluetooth adapter was inactive and could not be turned on
The Mediatek card mt7921 is an internal combined wifi and bluetooth
device and the wifi is unaffected in all kernels
I can resuscitate the bluetooth device:-
Close applications and power off
Remove the power cable
Press and hold the power button for more than 30 seconds
Re-attach power cable
Boot the PC
