Imre, any ideas?
Could you provide a full dmesg log starting from boot? The attached one is truncated. From what I can see, we try to enable some power well (the log shows at least TX-C-23) but the HW doesn't actually enable it. So it's either a punit problem, or that we don't use the proper HW knobs for the failing wells. Ville even had somewhere a comment that the mapping of TX power wells needs to be clarified against a HW with a working Punit and/or proper documentation. So I think we need to wait with a proper fix until we get a working CHV.

The remaining warnings are unrelated and tracked elsewhere, so closing this bug.
