Well, it caused problems to happen on one system only, but it did cause them
to happen and anyway it is not the final fix.

Right.

The (hopefully) final one is https://patchwork.kernel.org/patch/9189139/
and it still is pending a test on the Boris' machine where the previous one
didn't work.  If that doesn't pass, we'll need to defer it until we know
the reason and possibly make some additional changes before applying it,
so I'd rather route this one through the PM tree.
