Oh, then something else is causing my bug again, because I tried v3.13-rc3
to see if it has been fixed upstream. And, my Ubuntu runs on v3.11, where
the crashkernel does not work either.

My bisect ended up on 722bc6b16771ed8 because I started bisecting between v3.2
(good) and v3.5 (bad).

So, then I will make again a bisect between v3.7 and v3.11.


Thanks,
Christoph
