Please try installing using an image from here:

Greetings,

With the most recent weekly build, situation is following:

1. AX210 *WiFI* functions after removing the corresponding .pnvm file. Details are in the Arch FS #70071 [1]
2. Bluetooth does not work at all and indeed floods kernel ring buffer at the rate of >1 msg/sec. Message:

```
kern :info : [ +0.437457] usb 3-10: new full-speed USB device number 91 using xhci_hcd
kern :info : [ +0.150615] usb 3-10: New USB device found, idVendor=8087, idProduct=0032, bcdDevice= 0.00
kern :info : [ +0.000004] usb 3-10: New USB device strings: Mfr=0, Product=0, SerialNumber=0
kern :err : [ +0.004324] Bluetooth: hci0: Reading Intel version information failed (-22)
kern :err : [ +0.000006] Bluetooth: hci0: Intel Read version failed (-22)
kern :info : [ +0.000040] Bluetooth: hci0: Intel reset sent to retry FW download
kern :info : [ +0.000540] usb 3-10: USB disconnect, device number 91
```

Given that Arch FS link mentions issue as being resolved in 5.12.X, is there a chance to backport `linux-firmware` into 5.10.X LTS / Bullseye? AX210 is destined to be one of the most popular modules out there and this bug might cause some unnecessary bad press after the release.

Hi,

Could you confirm that the combination of the latest firmware and the
5.10 kernel solves this problem?

Best regards,
Nobuhiro

Hello Nobuhiro,

Unfortunately, I can't. Freshly updated Bullseye:

* linux-image-amd64: 5.10.46-2
* firmware-misc-nonfree: 20210315-2
* bluez-firmware: 1.2-4

Is there any additional information that might be helpful?
