Unfortunately many hardware vendors never correct BIOS but ships with some extra setup. I guess your problem is the same as discussed in the upstream bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=216194 I'll try to ping Cirrus people later. Meanwhile, I updated the test kernel with one more test patch. It's being rebuilt in the same OBS repo. The new kernel will be based on 6.0 (no longer rc7). Could you give it a try later once after the build finishes?
