Hello,

since 3.5, my crashkernel does not boot anymore when triggering an oops with
/proc/sysrq-trigger on my HP Elitebook 8540p.

I bisected it down to 722bc6b16771ed8 (x86/mm: Fix the size calculation of
mapping tables).


Does anybody has an idea what is going wrong here?
Let me know, if I should provide more information.


Thanks,
Christoph

It has been reverted in upstream.

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
