Description Neyzan 2018-04-08 16:16:27 UTC

Description of problem:
After upgrading the kernel to 4.15.14 and restarting the system I found all widgets I added in the panel removed (but not colour and style personalisation) and Blueman stopped functioning. In blueman's screen no devices were showing and the "Adaptor" and "Device" options in the toolbar were greyed out.
Other personal settings, such as recent documents in LibreOffice or browser history, were not affected.
Also, after re-adding the lost widgets to the panel in 4.15.13 they remained even after rebooting into 4.15.14, but blueman again stopped functioning.

Version-Release number of selected component (if applicable):
Distribution & Version: Fedora 27
Kernel: 4.15.14
Qt Version: 5.9.4
liblxqt Version: 0.11.1.7
Package version: 2.1.0.8alpha2 (Blueman), 5.48.3 (Bluez)

I upgraded to kernel 4.15.15 but the issue persists.

Comment 2 Neyzan 2018-04-21 12:28:11 UTC

I 've also reported this at Blueman's GitHub page:
https://github.com/blueman-project/blueman/issues/862

I hope the below provide adequate info. If not, please inform me what else is needed and how I may retrieve it.

Furthermore, "bluetoothctl list" gave no output, although Airplane mode is off (other networking methods function normally).

Running "bluetoothctl":

```
[bluetooth]# pair
Missing device address argument
[bluetooth]# head -1 $(which blueman-applet)
[bluetooth]#
```

Comment 3 Neyzan 2018-04-22 10:57:06 UTC

This seems to originate in this bug, so it's probably a kernel issue:
https://bugzilla.kernel.org/show_bug.cgi?id=199271

Comment 4 Raphael Groner 2018-04-23 05:57:52 UTC

As upstream confirms, I'll reassign to maintainers of kernel firmware. Though, no idea what concrete kernel module is responsible for bluetooth firmware.
