Still not working (I’m on the 6.15.8 kernel here). This version is still newer than the slowroll one but it should be the version I had when it was working. I installed TW ~Aug 10 and bt was working for at least a week after that while I was continuously installing all updates that came out.

22

Just to clarify, you rebooted (or at least reloaded the driver) after installing the older firmware?

23

Yes, rebooted

24

Any firmware errors to report?

Maybe this isn’t what you’re after? Please let me know if I should run some other command.

Also, like I mentioned earlier, the first two lines are likely the unsupported webcam and not related to this.

Unfortunately, this indicates firmware may be incompatible with the driver.

I think a bug report is in order.

Should I create one? If, so can you please provide some direction for where and how I do that? Thank you for helping me with this!

Some guidance
https://en.opensuse.org/openSUSE:Submitting_bug_reports

Login using same credentials as forum
https://bugzilla.opensuse.org/index.cgi

Product: Tumbleweed
Component: kernel:drivers

Mention kernel version and firmware version (current versions), dmesg output, bluetoothctl showoutput.

Also include the output from the following command (pertains to your BT device)…
usb-devices | awk 'BEGIN{RS=""; FS="\n"} /8c38/'

If you are using btrfs you can rollback to the snapshot that was working.

30

I am using btrfs, but unfortunately it doesn’t seem like Snapper has kept old enough snapshots.

I will get to creating that bug report very soon.

31

Ok, created a bug report now: 1249369 – Bluetooth adapter not found

32

Upstream kernel bug report

33

Problem fixed itself via an automatic BIOS update that I have no idea how it got installed (it just happened when I started up the laptop after it being shut down because of a flat battery). More info in the bug report.
