Public bug reported:
Bluetooth is completely non-functional on Ubuntu 26.04 LTS (Resolute
Raccoon).
When booting, the following errors appear in dmesg:
Bluetooth: hci0: Reading supported features failed (-16)
And in bluetoothd logs:
Failed to set mode: Failed (0x03)
No Bluetooth devices can be detected or paired. The adapter appears in
rfkill but cannot be activated.
System information:
- Model: HP ProBook 650 G2
- CPU: Intel Core i5-6200U (Skylake)
- Wireless/Bluetooth card: Intel Wireless 8260 (rev 3a)
- Kernel: 7.x.x-generic (from Ubuntu 26.04)
- Bluez version: 5.x
- OS: Ubuntu 26.04 LTS (Resolute Raccoon), fully updated
This is a regression; Bluetooth worked on older Ubuntu releases on this
hardware.
Additional info:
Output of `lsb_release -rd`:
Description: Ubuntu 26.04 LTS
Release: 26.04
Output of `apt-cache policy bluez`:
bluez:
Installed: 5.72-0ubuntu5
Candidate: 5.72-0ubuntu5
What I expected to happen:
Bluetooth should initialize correctly and allow pairing with devices.
What happened instead:
Bluetooth fails to initialize on every boot with the error:
Bluetooth: hci0: Reading supported features failed (-16)
