SOLVED Can't init device hci0: Connection timed out (110) after 6.11.1

gromit · 2024-10-20 09:35:50

This is the kernel with "Bluetooth: btusb: Fix not handling ZPL/short-transfer" reverted:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-lts-6.6.54-1.1-x86_64.pkg.tar.zst

This is a kernel with "Bluetooth: hci_core: Fix sending MGMT_EV_CONNECT_FAILED" reverted:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-lts-6.6.54-1.2-x86_64.pkg.tar.zst

Thanks a lot! I tested both, and I can say with confidence that with "Bluetooth: btusb: Fix not handling ZPL/short-transfer" reverted bluetooth works again

So, what now? This is a first time that I have a problem that requires patching a kernel. Do I use this build until the bug is fixed?

I think it was already reported: https://bugzilla.kernel.org/show_bug.cgi?id=219365
And there is a fix incoming: https://git.kernel.org/pub/scm/linux/ke … dadcaa8c7b

My Bluetooth also stopped working after upgrading the kernel to 6.11.4. Downgrading again to 6.10.9 got Bluetooth working again. Strangely enough, though, under both LTS kernels posted in this thread, Bluetooth works. It seems that only the combination of the two commits kill Bluetooth... Does that make any sense?

I'm not using a Bluetooth dongle, it's built-in:

I'm very happy to hear that! Thanks to you and @seth for helping me with this, I have so much respect for people like you who help make Linux better every day.
I will mark this thread as solved once I get the update where Bluetooth dongle works again

It's now working again with the latest kernel update (6.11.4-arch2-1).

Bluetooth: btusb: Fix regression with fake CSR controllers 0a12:0001 is queued for 6.11.5. If it helps I have built a kernel with that patch applied:
linux-6.11.4.arch2-1.1-x86_64.pkg.tar.zst/linux-headers-6.11.4.arch2-1.1-x86_64.pkg.tar.zst

Yes, I just installed the new kernel and Bluetooth appears to be working again. Hope it stays that way.

Doesn't work with mediatek.

Maybe it's a different problem.

Same errors as before:

Yes there are multiple known issues that are being conflated. Have you tried applying the Fix regression with fake CSR controllers 0a12:0001 https://bbs.archlinux.org/viewtopic.php … 5#p2203935 ?

Thanks for the test kernel.
It doesn't work with it.

systemd[1]: Bluetooth service was skipped because of an unmet condition check (ConditionPathIsDirectory=/sys/class/bluetooth).

I also can't get bluetooth to work on 6.11.1 2 3 or 4
Works on 6.10 all versions
Works on LTS

Did you see https://bbs.archlinux.org/viewtopic.php … 5#p2203185 resp. try "mt7921e.disable_aspm=Y"?

In doubt, open a new thread and post your entire system journal - no grepping.
The chip doesn't respond, but there's no indication as to why in the posted selection.

Thank you for your suggestion.
However it's the same with "mt7921e.disable_aspm=Y"

6.11.x also can't "Sleep". It doesn't wake and need a hard reset.
For now I'm staying on 6.10.10-arch1-1 or LTS where everything works.

There is a almost simular report here:
https://bugzilla.kernel.org/show_bug.cgi?id=219333

I'll keep an eye on that, cuz I'm not feeling cozy about posting a full journalctl

Resolved in 6.11.5

Gr.....
This issue is back on 6.17.8-arch1-1!!!!

I have a MT 7925 Wifi + Bluetooth built into my motherboard. It broke with the kernel discussed in this thread and now its back!
As in, the exact same error!

Reverting to 6.17.7 fixes it?
https://github.com/gregkh/linux/commits … th/btusb.c
https://github.com/gregkh/linux/commit/ … f0207cc7a5 is different from https://github.com/torvalds/linux/commi … 116a79c79e though.

https://github.com/gregkh/linux/commits … /bluetooth
=> https://github.com/gregkh/linux/commit/ … 87b06cf7bc (also different but braindead "KASAN told me so" patch)

Do you get any extra errors?

No, actually. Reverting to 6.17.7 doesn't work. Also I'm not sure what's happening but now dmesg refuses to acknowledged the existence of bluetooth on either stable or LTS.
I can force modprobe bt* or bluetooth and it'll cause /sys/class/bluetooth to be created but I still get nothing.
mt7925e tells me nothing

I have no idea what's happening anymore but bluetooth has went poof and now linux refuses to acknowledge that I even have BT hardware regardless of kernel.

AmericanPizza · Today 16:51:49

I downgraded to 6.17.7-arch[1,2] and linux-firmware-mediatek. Neither fixed it. dmesg tells me nothing.
It's like my bluetooth just doesn't exist anymore (which isn't possible since it's built into my motherboard).

I'd like to add that my device is over PCI(e) and not USB.
