Re: linux-6.11.4.arch1-1 breaks bluetooth

The only machine I have access to with enough oomph to (re)build the kernel multiple times is currently tied up developing some ESP32 firmware. Hopefully I will be able to spend some time over the weekend. I had a look through the (surprising long) changelog for 6.11.3 at https://cdn.kernel.org/pub/linux/kernel … Log-6.11.3 and might try to cherry pick some commits (thanks @seth) before trying a full bisect cycle.

If you want some help with the bisection before the weekend gromit or I could build bisection kernels for you.

$ uname -a
Linux skunk-develop 6.12.0-rc4-1-mainline #1 SMP PREEMPT_DYNAMIC Mon, 21 Oct 2024 00:01:57 +0000 x86_64 GNU/Linux

Works fine here. Hopefully none of the bad commit(s) will migrate into mainline and pollute it.

Re: linux-6.11.4.arch1-1 breaks bluetooth

@loqs, do you have a PKGBUILD for building the archlinux kernel out of git?

diff of changes to build 6.11.3 from upstream kernel.org from git does it need to be Arch's tag?

Re: linux-6.11.4.arch1-1 breaks bluetooth

It's anecdotal, but 6.11.4 seemed to have solved the problem for me on my Framework 13 AMD. However, 6.11.5 has at least partially brought back the problem. I'm able to re-pair and connect with some devices, but my Apple Magic Trackpad will not connect, not matter what I try.

Re: linux-6.11.4.arch1-1 breaks bluetooth

@loqs, not necessarily.
I had imagined you were bisecting github.com/archlinux/linux to incorporate the downstream patches relevant to each minor release (cause that's what the users initially face), but in the grand scheme of things, they're probably rarely causing major differences for the bisection tests.

Thanks for the diff.

Re: linux-6.11.4.arch1-1 breaks bluetooth

Bisecting github.com/archlinux/linux takes slightly more work to setup as that repo does not contain the kernel.org tags which leads to confusing version strings so kernel.org stable needs to be added as as well and the tags fetched.

Re: linux-6.11.4.arch1-1 breaks bluetooth

6.11.6 + new bluez, and all my devices are working as expected. Thanks, all.
