Details

Description: From Linux kernel upgrade 5.15.0 to current kernel version bluetooth manager reports 'No adapter(s) found after quick rebooting the machine. :% bbOnly solution is to cold boot i.e. shutdown and disconnect the power cord for 20 secs and reboot. Problem appears not to be a power management issue. I have been through the kernel downgrades and the last kernel where problem did not occur is 5.14.16. The problem has also occurred occasionally with a USB 3 port; again a cold boot solves this.


Additional info:
* package version(s) Problem kernel versions: 5.15.0 to current; last working version 5.14.16, blueman 1:1.2.11-4
Machine: Lenovo T450s; proprietary Intel Corp. Bluetooth wireless interface. ATTR{vendor}==0x8087, ATTR[device}==0x0a2a

* config and/or log files etc.
