Created attachment 298013 [details] dmesg log after warm and cold boot Hello, The AX 210 Bluetooth controller does not get initialized after a warm boot. It gets initialized after a cold boot had been performed (going to the BIOS menu, doing nothing and leaving it, afterwards starting Linux). In both cases the bluetooth USB See dmesg logs attached. Regards, Tobias Predel
In both cases the bluetooth USB device is recognized on the bus.
Saw this behavior on 5.13.8 (.arch1-1) Rolling back to 5.12.15, the issue is not present.
I'm also seeing this issue in 5.13-10 (-arch-1). Cold booting consistently fixes it, and rolling back to 5.12.15 fixes the warm booting problem.
I have verified this issue is still present in 5.14.0 (and not present in 5.12.19)
I've experienced this issue as well since the 5.13.6 update which persists in 5.14.2. Cold booting each time allows Bluetooth to function, although the device is recognized (but not functional) with regular warm boots.
On 5.14.9 the bluetooth adapter still doesn't work. 5.12.15 from 07 Jul 2021 is the last kernel working before the regression. I could reproduce this regression consistently on 2 machines for a quarter now... do we know if we have anyone looking into it?
Just swapped a not great wifi card with a brand new AX210 and yes, same problem on my system, dmesg log identical to the one above, if the firmware is already loaded on the card. Can anyone from Intel take a look at this problem? Thanks.
looks like it start working correct with latest firmware (https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/intel/ibt-0041-0041.sfi) on linux 5.14.12
I can confirm that this is no longer issue in 5.14.12. linux-firmware 20210818
Running on 5.15.0-rc5-1 and linux-firmware 20210919.d526e04-1 I'm still having this issue.

I continued to investigate. The major difference between a cold boot and a warm boot is the driver trying to load a firmware. For the science, I just disabled this behavior and it looks like the device and driver recover on a warm boot. Consider this a workaround and not a fix but at least it works for me, bluetooth is available on a warm boot. ``` pal ➜ linux-5.14.12 diff -u drivers/bluetooth/btintel.c.old drivers/bluetooth/btintel.c --- drivers/bluetooth/btintel.c.old 2021-10-17 13:56:23.583338189 -0400 +++ drivers/bluetooth/btintel.c 2021-10-17 14:01:16.113344330 -0400 @@ -1034,17 +1034,6 @@ /* Skip reading firmware file version in bootloader mode */ if (ver->fw_variant == 0x06) break; - - /* Skip download if firmware has the same version */ - if (btintel_firmware_version(hdev, ver->fw_build_num, - ver->fw_build_ww, ver->fw_build_yy, - fw, boot_param)) { - bt_dev_info(hdev, "Firmware already loaded"); - /* Return -EALREADY to indicate that the firmware has - * already been loaded. - */ - return -EALREADY; - } } /* The firmware variant determines if the device is in bootloader @@ -1074,21 +1063,6 @@ int err; u32 css_header_ver; - /* Skip reading firmware file version in bootloader mode */ - if (ver->img_type != 0x01) { - /* Skip download if firmware has the same version */ - if (btintel_firmware_version(hdev, ver->min_fw_build_nn, - ver->min_fw_build_cw, - ver->min_fw_build_yy, - fw, boot_param)) { - bt_dev_info(hdev, "Firmware already loaded"); - /* Return -EALREADY to indicate that firmware has - * already been loaded. - */ - return -EALREADY; - } - } - /* The firmware variant determines if the device is in bootloader * mode or is running operational firmware.

Just tested with the latest firmware, reboot, firmware already loaded message and no response again from the bluetooth subsystem, even if it's present in the usb tree no bluetooth adapter detected from my DE. According to the point that began to have the issue, I suspected already that the issue in the code stems from the not reupload of the firmware to the adapter, good that removing the firmware check fix the issue, but this is not the proper way to go. Intel should properly check why it doesn't work for some (I assume). Marco.

After updating to 5.14.15, it got even worse, now it will literally drop the connection with my mouse after 10 seconds and it will stop responding to any command until a complete shutdown, all I get in the logs is a command timeout, it will literally stop responding to my host.

This was fixed after a reinstall of linux-firmware, sorry, the problem after a reboot is still there, though.
Can confirm the issue still exists with 5.14.15.
This should be fixed with https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/bluetooth/btintel.c?id=35191a0fe986bacf69bd842de81119dca7970f11 I tried it with 5.15 and didn't see the problem.

Sorry it is not. Testing with the framework laptop on testing/linux 5.15.1.arch1-2 Steps to reproduce: 1. go to the bios and save settings, it starts bt correctly. 2. Just reboot with for example the reboot command or come out of hibernation etc... it fails as usual.

Still confirm that after upgrading gcc to 11.2.0 this issue gone for me. I'm now on 5.14.17.
5.15.2-arch1-1 still suffers from the issue. I can't even get a list of devices after a cold boot...
Could you try with the latest firmware from linux-firmware.git? https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git Copy the intel/*.sfi to /lib/firmware/intel/ and cold boot. It will help to rule out if it is fw issue or not.

I just tried. I installed the latest linux-firmware-git package that pulled latest. On cold boot I had `bluetoothctl list` hang after boot. Then after restarting the bluetooth service, it showed the device but still refused to even do a basic scan. `Failed to start discovery: org.bluez.Error.NotReady` Then after doing another quick cold boot (stayed off only a few seconds), no device was listed at all. =\

With the latest firmware (just downloaded ibt-0041-0041.ddc and sfi, but if the wireless portion is needed, I can add that too) and that made things even weirder and weirder. After a cold boot, the adapter was working as standard. Rebooted and the device was disabled by default (my machine is configured to auto enable the bluetooth at boot), but after disabling and reenabling the radio from my DE, the bluetooth reconnected to my mouse for the first time since I've got this adapter under Linux. After another reboot, the radio completely disappeared (not even detected from my DE). I don't really know where the problem resides, but I'm happy that someone is trying to see to the bottom of this. Marco.
Alright, talking with Intel directly, this patch seems to fix it for 5.15.2: https://patchwork.kernel.org/project/bluetooth/patch/20211013080511.23945-1-kiran.k@intel.com/ I have a bunch of other regressions like GPU hangs with 5.15 but at least I see the controller showing up consistently warm reboot after warm reboot. Can anyone else confirm it works?

Nope, running 5.15.2 and now bluetooth disappears after a reboot. This hasn't fixed the problem for me, it just changed behaviour. I can confirm that the patch is present, I do see the message added for that patch: ...

But there is no bluetooth adapter available from both my DE nor from bluetoothctl info command.
The message above with the aforementioned errors are simply after a sleep-wake cycle of my system, bluetooth is dead as before.

After compiling 5.15.2 plus the above mentioned patch, I can definitively confirm that on my system the issue is completely fixed. Rebooted 5 times, each time the bluetooth was working correctly. Finally this bug is fixed, I hope it will be merged soon, at least on the 5.15 series. Thanks a lot for your work, Marco.
I really hope this patch merges soon as well. What is the best way to be notified when it lands?
PSA: Just tried with 5.15.3, still not good (I am not sure which version the patch it targeted for).
At least for Arch Linux user, this is now included in linux-zen (>=) 5.15.4.zen1-1 kernel See: https://github.com/zen-kernel/zen-kernel/commit/b7320bcb94e0736064e8e39b9e7466e38fb4a161 And I can also confirm that it fixes the problem.

It is fixed in Arch Linux though. I'm using 5.15.4.arch1-1, not the zen kernel. See https://github.com/archlinux/linux/commit/236027c0ae73217898ac8249e44394cc1026dada Let's hope it will soon land in the mainline kernel too.
I faced a similar issue (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000403) on Debian unstable, but only with v5.15.3. When I built v5.15.4 of the kernel, it went away. > It is fixed in Arch Linux though. > I'm using 5.15.4.arch1-1, not the zen kernel. > > See > https://github.com/archlinux/linux/commit/ > 236027c0ae73217898ac8249e44394cc1026dada Applying this patch on 5.15.3 didn't resolve this for me, but simply moving to 5.15.4 did. > > Let's hope it will soon land in the mainline kernel too.
I confirm that it's working with 5.15.5-arch1-1
While under 5.15.6, and after accidentally left the latest bluetooth firmware on linux-firmware from all the previous tests, the reboot works, but after 10 to 15 seconds of boot time when my mouse get connected correctly the adapter completely dies and become completely unresponsive, the device stops completely responding to any input from my DE. Logs attached. After a reboot sometimes the adapter come back to life for the aforementioned 15 to 30 seconds before dies again. Other times the actual adapter disappears from the system. Initially I thought that this bug has come back, but after replacing the latest firmware and seeing that the driver told me that it was already uploaded to the adapter, I then downloaded linux-firmware and replaced the firmware blobs everything seems to work correctly again. I hope that some changes are missing for this new firmware in the linux kernel, otherwise AFAICS this will break my setup again.

Disregard this, I've tried with the original adapter and the bug is still identical. Apparently my AMD APU laptop has some issues with USB devices after a while, but only with the internal USB bus on the M.2 port and not with the external USB ports. I've checked for firmware updates for this platform, but I've already the latest version. I've checked the AGESA version and it seems to still be stuck to 1.0.0.8, according to the SMU version number (I know of the dreaded USB reset bus under load, but this happens even on idle, so I don't really know). Weird, Marco.
Well, after the 5.15.8 update of yesterday, the random disconnects seems to be gone. Usually the adapter stopped working after around one hour until I put it to sleep and wake it up again. Now it's basically passed 10 hours without any issues. Weird, but good for me I guess. Hope to see this patch merged soon.
After having been fixed for 5.15 series, the issue seems to reappear on linux mainline 5.16, at least on rc 7. Bluetooth only works after cold boot, but not after warm boot. Can anyone look into this?

On 5.15.12 arch if i do a reboot i get no bluetooth. The PC needs to be shutdown and then turned on again for it to work. And even when its working it is a bit wonky. I get it to throw errors in the journal and stop working. Hopefully a firmware update in the next kernel will fix that.

Same here, can't see any issues after a reboot. About the errors, I mentioned this a few posts above #41, but this happens on another Bluetooth adapter version, so I'm not really sure where the problem lies here. AFA I can remember, since 5.15.8/9 I haven't seen this issue back, so I'm not really sure if it's the same problem (randomly stop working, the whole Bluetooth device stop responding to the Linux kernel). Marco.

Same issues as mine, are you on a Ryzen or Intel? As far as I have previously debugged, I wasn't unable to pinpoint the cause, since it was happening randomly also on a Realtek radio, so it was either the Bluetooth driver or an actual platform issue (but the external USB ports was still working correctly, therefore I had never been able to find the root cause). Marco.
Its an intel based laptop. Samsung Galaxy Book Pro 13 to be exact. Since you said the usb port works correctly then its a BT issue probably. I cant verify that myself though since its internal in my case. Anyway. Hopefully a future update will fix that.
Looking into the logs i also get: Ιαν 06 01:08:24 mainland bluetoothd[448]: Failed to set mode: Blocked through rfkill (0x12) Ιαν 06 01:08:31 mainland bluetoothd[448]: src/profile.c:record_cb() Unable to get Hands-Free Voice gateway SDP record: Host is down But i am not sure what is related to it.

Yea, since you are on a completely different platform at this point i'll suspect this is probably a generic Bluetooth driver issue. Hope that this will be fixed sooner or later.
An update to 5.15.13 kind of fixed this. It starts when rebooted but its slower than a cold start. Ie when i start my DE BT is there for the cold start but appears after a little while for the reboot case. As for the loss of bluetooth bug what i found out after looking a bit more into the logs was that i get this: kernel: usb 3-10: Failed to suspend device, error -110
