This becomes a monologue :-/
Bisect found the breaking change to be in:

f813fe810fc3f0ce839f450e662e0173d40a5ce1 is the first bad commit

   storage: backend: Refactor registration of the backend drivers

   Add APIs that allow to dynamically register driver backends so that the
   list of available drivers does not need to be known during compile time.

   This will allow us to modularize the storage driver on runtime.


I'll try to debug in more detail how/where it broke it, but since this is a
rather huge refactor and not a small change this might take a while. Any
hints still welcome.
