I am running an alder lake i7 1260P with built-in bluetooth. This adapter always worked fine with no special config, but since I booted Linux 6.7, the device completely disappeared. There's no mention of bluetooth in the kernel or system logs, there's no device node, and there's no entry in lspci. When I boot the last working kernel again (6.6.10), the device also doesn't appear (even though it did before, see logs below).
I also tried booting a ubuntu live ISO to exclude any configuration issues with my distro's (NixOS) kernel or such, and also there the device did not show up.
I am not sure at all that this is related to the kernel, but I wouldn't know where else to look. I am including below my system logs (journalctl -g 'blue|Blue|Linux') showing the kernel version and the bluetooth related entries. As you can see, on 6.6.10 the bluetooth module got loaded, /dev/hci0 gets created, and user space sets up the bluetooth stack.
The next boot entry is the first time I booted 6.7, and there's no mention of bluetooth at all in the logs. I tried to load the bluetooth module manually, which succeeds but doesn't create a device node.
When I boot 6.6.10 again now, I get exactly the same as on 6.7. I don't know if the kernel could have done anything persistent to the device that makes that it doesn't get initialised anymore?
I'm not sure how to debug this further, let me know if there's a way to get more detailed info in the kernel logs or such.
Thanks, Ramses

I forgot to add the full kernel logs, attached the logs of 6.6.10 with working bluetooth and 6.7 where bluetooth is not working.
I am also including a recent boot with 6.6.9 (after having booted with 6.7) where bluetooth is also not showing up, even though it did work before on the same kernel build.
Thanks, Ramses

I forgot to add the full kernel logs, attached the logs of 6.6.10 with working bluetooth and 6.7 where bluetooth is not working.
Hi! This is not my area of expertise, but as it seems nobody answered let me give it a shot:
It seems you are using different firmware files for you Wifi device (compare the lines "iwlwifi 0000:01:00.0: loaded firmware version..."); could you maybe temporarily remove the newer one to rule out it causes your BT problem?
There are a few other differences in the dmesg that look odd; the older one has lines like "input: Kensington Eagle Trackball", the newer one does not. Did you disconnect that device in between? If not it sounds like there is something fishy somewhere, maybe with USB or your kernel config.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
I am also including a recent boot with 6.6.9 (after having booted with 6.7) where bluetooth is also not showing up, even though it did work before on the same kernel build.
Thanks, Ramses
Jan 13, 2024, 14:38 by ramses@well-founded.dev:
I am running an alder lake i7 1260P with built-in bluetooth. This adapter always worked fine with no special config, but since I booted Linux 6.7, the device completely disappeared. There's no mention of bluetooth in the kernel or system logs, there's no device node, and there's no entry in lspci. When I boot the last working kernel again (6.6.10), the device also doesn't appear (even though it did before, see logs below).
I also tried booting a ubuntu live ISO to exclude any configuration issues with my distro's (NixOS) kernel or such, and also there the device did not show up.
I am not sure at all that this is related to the kernel, but I wouldn't know where else to look. I am including below my system logs (journalctl -g 'blue|Blue|Linux') showing the kernel version and the bluetooth related entries. As you can see, on 6.6.10 the bluetooth module got loaded, /dev/hci0 gets created, and user space sets up the bluetooth stack.
The next boot entry is the first time I booted 6.7, and there's no mention of bluetooth at all in the logs. I tried to load the bluetooth module manually, which succeeds but doesn't create a device node.
When I boot 6.6.10 again now, I get exactly the same as on 6.7. I don't know if the kernel could have done anything persistent to the device that makes that it doesn't get initialised anymore?
I'm not sure how to debug this further, let me know if there's a way to get more detailed info in the kernel logs or such.
Thanks, Ramses

Hi! This is not my area of expertise, but as it seems nobody answered let me give it a shot:
It seems you are using different firmware files for you Wifi device (compare the lines "iwlwifi 0000:01:00.0: loaded firmware version..."); could you maybe temporarily remove the newer one to rule out it causes your BT problem?
There are a few other differences in the dmesg that look odd; the older one has lines like "input: Kensington Eagle Trackball", the newer one does not. Did you disconnect that device in between? If not it sounds like there is something fishy somewhere, maybe with USB or your kernel config.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
I am also including a recent boot with 6.6.9 (after having booted with 6.7) where bluetooth is also not showing up, even though it did work before on the same kernel build.
Thanks, Ramses
Jan 13, 2024, 14:38 by ramses@well-founded.dev:
I am running an alder lake i7 1260P with built-in bluetooth. This adapter always worked fine with no special config, but since I booted Linux 6.7, the device completely disappeared. There's no mention of bluetooth in the kernel or system logs, there's no device node, and there's no entry in lspci. When I boot the last working kernel again (6.6.10), the device also doesn't appear (even though it did before, see logs below).
I also tried booting a ubuntu live ISO to exclude any configuration issues with my distro's (NixOS) kernel or such, and also there the device did not show up.
I am not sure at all that this is related to the kernel, but I wouldn't know where else to look. I am including below my system logs (journalctl -g 'blue|Blue|Linux') showing the kernel version and the bluetooth related entries. As you can see, on 6.6.10 the bluetooth module got loaded, /dev/hci0 gets created, and user space sets up the bluetooth stack.
The next boot entry is the first time I booted 6.7, and there's no mention of bluetooth at all in the logs. I tried to load the bluetooth module manually, which succeeds but doesn't create a device node.
When I boot 6.6.10 again now, I get exactly the same as on 6.7. I don't know if the kernel could have done anything persistent to the device that makes that it doesn't get initialised anymore?
I'm not sure how to debug this further, let me know if there's a way to get more detailed info in the kernel logs or such.
Thanks, Ramses

Hi Thorsten
Thanks a lot for your reply!
I was initially hoping that it was simply a version issue, but when I compiled and booted 6.6.9, with the same iwlwifi driver version that I had before, Bluetooth was still not working (the dmesg for that boot was attached to the original email).
So I was hoping that there's maybe some microcode or other persistent state or such that may explain why the Bluetooth suddenly disappeared, as the only other option that I can think of, would be sudden hardware failure (not sure if that happens, I haven't heard of that with integrated chips).
Thanks again for your reply, I appreciate it! Ramses
