GCC13.1 is mainlined in arch, so this means znver4 support can kick off on this kernel. The graysky compile patches have been updated too.

This kernel now natively supports the znver4 arch, but this kernel will most likely keep working on all AMD ryzen hardware. It's better to be able to address certain small perks or issues per architecture now and in the future.

If you use znver3 based hardware, please use linux-amd-znver3
If you use znver2 based hardware, please use linux-amd-znver2
If you use raven based hardware, please use linux-amd-raven

i fail to install v4l2loopback-dkms (from official repository) module with this kernel and headers:

The v4l2loopback-dkms-git package seems to run in the same problem during build.

Does someone have any clue on this?

@eggz After upgrade to 5.16.13 rebooted my machine and, as expected, no Bluetooth. I recalled your idea of rmmods and insmods and ... it works. It seems to me a timeout too short.

Thank you very much for your time and efforts.

Regards.

Sound reasonable.

What you are experiencing there is the fact that the bluetooth has its own firmware running. And As long if you dont shut the system down completely (power it down), that firmware will keep being in the same state.

Trust me: I don't believe in ghosts (not even a little bit) but:

1. Using linux-amd no Bluetooth.
2. Restarted with linux-zen and Bluetooth is working.
3. Restarted with linux-amd to rmmod and insmod (as you mentioned) but no need because Bluetooth is working.

So ... Sorry about the noise.

Mentioned patches do not guarantee a 100% workaround as far as I could see. This has yet to be researched, concluded and fixed upstream before I think its worth it for me to make any sort of adoption...

As for now, does spamming this make it work after a few tries? I'm just curious..

rmmod btusb
rmmod btintel
modprobe btintel
modprobe btusb

Just as a reference, Bluetooth is working correctly with linux-zen 5.16.12.zen1-1 and WAS working with previous versions of linux-amd. Maybe it's related to these posts "https://bbs.archlinux.org/viewtopic.php?id=271459" and the problem comes from upstairs.

Regards.

I dont have any Intel BT hardware around afaik, I only see this in the config:

CONFIG_BT_INTEL=m
CONFIG_BT_HCIUART_INTEL=y

It's enabled. That's all I know. Sorry... :-(

@eggz Hi, I'm on the latest kernel (-2) and having a problem with Bluetooth "Bluetooth: hci0: Reading Intel version command failed (-110)"

Are you aware of this? Is there something I can do to solve this problem?

Thank you very much for your time and efforts.

Regards.

I have -3 installed, looks like I just missed the update, ill start a recompile.
