--- Comment #51 from Jani Nikula <jani.nikula at intel.com> ---
Looking at the results, the 4 lane configurations work, but 2 lane
configurations don't. This is also true for 5.4 GHz, indicated by
bug76711-prefer-fast-and-wide vs. bug76711-nightly. The dmesg and reg dump
differences between the two are minimal, yet crucial. Investigation continues.
