Created attachment 1730086 [details]
Dmesg since boot

1. Please describe the problem:
After upgrading a fresh install of Fedora 33 (kernel 5.8.15-301) to kernel 5.9.8-200, triggering the bluetooth on/off switch in both the control center and the applet does not have any effect.


5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
Did not test yet

6. Are you running any modules that not shipped with directly Fedora's kernel?:
No

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.
See attached dmesg.txt
Comment 1 fhortner 2020-11-17 10:53:01 UTC 
seems to be a kernel issue, since also other distros are affected.
Seems to be an issue with the kernel trying to use Link-Layer Privacy for BLE devices

see bugzilla.kernel.org:

*** This bug has been marked as a duplicate of bug 1897038 ***
Comment 3 michele.riva 2020-11-17 14:08:05 UTC 
Actually, I can't even reach the pairing step thus it might be something related, yet different. Gnome's control panel simply shows that bluetooth is turned off, event though the switch on the top right corner is on, thus no device is listed (and probably not even scanned).
Comment 4 michele.riva 2020-11-20 19:05:47 UTC 
I confirm this bug is NOT solved by kernel 5.9.9-200.fc33 from https://bodhi.fedoraproject.org/updates/FEDORA-2020-febe24a7ca
This is a different issue than bluetooth pairing.

Comment 6 Michael Carney 2020-11-20 21:06:08 UTC 
I can also confirm that kernel 5.9.9-200.fc33 *DOES NOT* fix this problem -- it still remains (bluetooth is completely disabled). This bug is NOT a duplicate of 1897038 - it has nothing to do with pairing. Please reopen this bug.

Returning to 5.8.18-300.fc33 restores bluetooth functionality.
Comment 7 Michael Carney 2020-11-20 21:13:45 UTC 
I'm using the KDE spin.

michele, can you reopen this bug as submitter? I want to make sure that any realtek bluetooth adapter users see this. Thanks.

Comment 17 Rui Miguel Seabra 2021-01-17 19:12:30 UTC 
I don't think this caught all the recent bluetooth issues...

# uname -srvmpio

I need to reboot in order to be able to reconnect to my bluetooth headset.
Comment 18 Rui Miguel Seabra 2021-01-17 19:17:04 UTC 
Sorry, reconnect is not the correct term, it connects, it's just that the sound profile never gets set to a2dp.

But the sound still comes from the laptop's speakers.

Unsure of how to specify by command, I go to the Gnome Shell's sound settings, verify that it says "speakers" and specify the proper headset output device...

BUT the sound still comes from speakers.

I'm going two kernels backward to kernel-core-5.9.13-200.fc33.x86_64 in order to check if it works better.
Comment 20 Rui Miguel Seabra 2021-01-17 19:26:24 UTC 
Nopes, same behaviour.
Comment 21 Rui Miguel Seabra 2021-01-17 19:29:35 UTC 
Ah... it seems that the gnome shell settings application is sending the test to the speakers, but sound is indeed coming from the headset! confusing for users, though. very confusing.
Comment 22 trubonru 2021-03-18 07:49:30 UTC 
I can confirm this bug. Device succsessfully connect to my wireless headset (Headset play a sound that signalaize that device is connected). But sound still goes from laptop speakers. there is also no sound profile for headset in my gnome sound settings
