With Linux Kernel 7.0.7 Bluetooth stopped working

It was working with Kernel 7.0.5 just about yesterday

Just updated to Kernel 7.0.7 and bluetooth died.

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

Can confirm the same thing, just updated to 7.0.7-arch1-1 and my bluetooth has stopped working entirely. Motherboard: MSI MAG B650 TOMAHAWK WIFI. I have pretty much the same output in journals and bluetoothctl. The problem seem to be related to the MTK driver, I tried to plug my old RTK Bluetooth dongle and it works fairly well. Tried to boot into linux-lts kernel, the onboard wireless chip works just fine there.

It's the same on my Geekom A8. Bluetooth doesn't work with kernel 7.0.7.

downgrading to 7.0.6 worked for me, i'll just wait until this is fixed before upgrading.

Already tried everything:
1) Restarting services
2) Restarting kernel modules
3) Reinstalling firmware package
etc... nothing's changed. The bluetooth still won't work with MediaTek chips for me. The only thing that helped is booting into linux-lts.

Face the same issue on Zen kernel and LTS kernel for the Mediatek adapter.

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

I can confirm the issue, not only for linux 7.0.6.arch1-1 -> 7.0.7.arch1-1 upgrade, but also for linux-lts 6.18.29-1 -> 6.18.30-1 upgrade.
Internal Intel AX210 Bluetooth wasn't affected, but the external MediaTek USB WiFi+Bluetooth combo was - external Bluetooth stopped working.
Looks like some structural change (regression?) has landed to linux and linux-lts kernels.

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

Is there anybody outthere who can "translate" the patch

https://git.kernel.org/pub/scm/linux/ke … d2f604c78b

into terminal orders and activities

You have to either compile the kernel with this patch yourself or wait until like next week for the fix to reach the stable branch.

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

Heads Up: There's been an update (Linux 7.0.7-arch2-1) but issue still persists.

I'm also on 7.0.7-arch2-1, still not working for me. Has anyone been able to try the patch?
On the Arch GitLab a dev said a patch got picked up into 7.0.8.arch1. Are there any solutions besides waiting?

As I already said, your only solution besides waiting is to build the kernel from sources yourself. Building might take somewhere between 30 minutes and few hours depending on your hardware. But I would not recommend you to build the kernel yourself if you don't know what you're doing so the best solution is to wait.

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

linux-7.0.8-arch1 did got pushed, but it's still in core-testing. In order to get it you have to enable core-testing repository for pacman, in case anyone wants to get it ahead of time

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

I've updated to linux-7.0.8-arch1 and the MediaTek bloetooth adapter is available and functional again.
I noticed that linux-lts is upgraded from 6.18.30-1 to 6.18.31-1, I assume that the issue is fixed there as well, but haven't tested it.

Nobody here explained how to downgrade not needed anymore but: sudo pacman -U file://var/cache/pacman/pkg/linux-7.0.5.arch1-1-x86_64.pkg.tar.zst

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

I have a similar problem but tried to fix it on my own but it still persisted, i disabled the onboard bt and added a pcie bluetooth device and it work for a while then gave the same problems so i did a fresh install and tried again and for some reason my bluetui wouldn't start and bluetooth wouldn't stay on so i did another fresh minimal install and removed my hard drives just incase they were a problem and flashed both of my m.2 ssd's and now it still won't stay connected for more than 10-20 seconds

Re: With Linux Kernel 7.0.7 Bluetooth stopped working

This thread was about a problem with mediatek BT devices that should be fixed as of 7.0.8-arch1 if you are on that kernel an can still reproduce you most likely have a different issue and should post a new thread with more details on which exact BT controllers are involved.

And post the entire journal not just an excerpt and use  [code][/code] tags when pasting outputs
