Bingo, that was the problem in my setup: as the patch was applied
through a script with others, I had missed the error message about the
conflict (I have also another conflict which can be safely ignored so
the new one did not catch my eye)... So the patch was only half-applied,
and the final code is broken.

How did you solve the conflict (I am not a scheduler expert)? I can
retry running the patched kernel with your resolution, to check if
everything is ok.
