> 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.

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

Best regards,
