Description George Sapkin 2018-01-16 08:59:49 UTC

Version-Release number of selected component (if applicable):

bluez-5.48-1
iwl7260-firmware-25.30.13.0-82
kernel-4.14.8-300
linux-firmware-20171215-82.git2451bb22


Steps to Reproduce:
1. Upgrade bluez from 5.47 to 5.48
2. Try to turn on Bluetooth and pair or connect to any device


Actual results:

Bluetooth status is not reflect in notification area or Settings screen until it is opened again. Bluetooth appears to be non-functional.


Expected results:

Bluetooth works as expected


Additional info:

Downgrading to bluez 5.47 immediately resolves the issue. Bluetooth however has been mostly broken on Fedora 27 for a while now so it might be something else.

Possibly a duplicate of bug 1534857.

Comment 2 George Sapkin 2018-02-01 14:42:33 UTC

It's not just the audio that stops working.
