Whe= n I installed TW on my HP ZBook Ultra 14 G1a (AMD Strix Halo) around Aug 10 it worked as expected. It stopped working at some point but I don't know when because I wasn't using any BT devices for a couple of weeks, until Sep 8. I was directed here by distro maintainers after filing a bug there: https://bugzilla.opensuse.org/show_bug.cgi?id=3D1249369 I initially created this forum thread, which contains some more info: https://forums.opensuse.org/t/bluetooth-adapter-not-found-used-to-work/1879= 41 I have tried the following kernel versions: - 6.17-rc5 - 6.16.5 - 6.16.3 - 6.16.1 - 6.15.8 (version when I initially set up the machine) - 6.12.45 I have also tried kernel-firmware-mediatek 20250804-1.1 in combination with= the 6.15.8 kernel (in addition to the 20250903-1.1 version) without seeing any differences. Some more info (all from after booting 6.16.5), and I'm also attaching full dmesg from immediately after boot: $ bluetoothctl show No default controller available $ sudo rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no $ sudo hwinfo | grep -E "blue|Blue|BLUE"=20=20=20 P: /devices/pci0000:00/0000:00:08.3/0000:c5:00.0/usb3/3-5/3-5:1.0/bluetooth/hc= i0 J: +bluetooth:hci0 U: bluetooth E: DEVPATH=3D/devices/pci0000:00/0000:00:08.3/0000:c5:00.0/usb3/3-5/3-5:1.0/bl= uetooth/hci0 E: SUBSYSTEM=3Dbluetooth E: SYSTEMD_ALIAS=3D/sys/subsystem/bluetooth/devices/hci0 E: SYSTEMD_WANTS=3Dbluetooth.target E: SYSTEMD_USER_WANTS=3Dbluetooth.target P: /devices/pci0000:00/0000:00:08.3/0000:c5:00.0/usb3/3-5/3-5:1.0/bluetooth/hc= i0/rfkill0 E: DEVPATH=3D/devices/pci0000:00/0000:00:08.3/0000:c5:00.0/usb3/3-5/3-5:1.0/bl= uetooth/hci0/rfkill0 E: RFKILL_TYPE=3Dbluetooth /devices/pci0000:00/0000:00:08.3/0000:c5:00.0/usb3/3-5/3-5:1.0/bluetooth/hc= i0 /devices/pci0000:00/0000:00:08.3/0000:c5:00.0/usb3/3-5/3-5:1.0/bluetooth/hc= i0/rfkill0 bluetooth 1056768 15 bnep,btusb,btrtl,btintel,btbcm,btmtk, Live 0xffffffffc0ca1000 rfkill 45056 10 mt7925e,hp_wmi,cfg80211,bluetooth, Live 0xffffffffc0c9e000 crc16 12288 2 bluetooth,amdgpu, Live 0xffffffffc0c9c000 103: USB 00.2: 11500 Bluetooth Device Hardware Class: bluetooth 107: USB 00.0: 11500 Bluetooth Device Hardware Class: bluetooth 114: USB 00.1: 11500 Bluetooth Device Hardware Class: bluetooth $ usb-devices | awk 'BEGIN{RS=3D""; FS=3D"\n"} /8c38/'=20=20=20=20=20 T: Bus=3D03 Lev=3D01 Prnt=3D02 Port=3D04 Cnt=3D01 Dev#=3D 3 Spd=3D480 Mx= Ch=3D 0 D: Ver=3D 2.10 Cls=3Def(misc ) Sub=3D02 Prot=3D01 MxPS=3D64 #Cfgs=3D 1 P: Vendor=3D0e8d ProdID=3D8c38 Rev=3D01.00 S: Manufacturer=3DMediaTek Inc.
