AVM FritzBox Lantiq-VRX200 and ADSL2+

Installing and Using OpenWrt

Maybe this ? Since after 22.03.0-rc4 OpenWrt introduced support to:

Vectoring on Lantiq VRX200 / VR9 - missing callback for sending error samples - For Developers - OpenWrt Forum

So few ADSL/ADSL2+users here are able to test recent changes.
But I assume old fw like 22.03.0-rc1 would work .
Please also test 22.03.0-rc4 if possible.
If we can point any version from where it stopped to work that would be great improvement to bug hunters.
