The microSD card detect pin is physically connected to the MPU pin PI3.
The Device Tree configuration of the card detect pin was wrong—it was
set to pin PB7 instead. If such configuration was used, the kernel would
hang on “Waiting for root device” when booting from a microSD card.

A gentle ping. FWIW, there was another patch that would deal with the
same issue:
<https://st-md-mailman.stormreply.com/pipermail/linux-stm32/2021-April/011132.html>,
but it took the more radical approach of of replacing cd-gpios with
broken-cd.
