As per [1] and our recent discussions the generic 4.x kernels seem to no

Bisection leads to:

dca496451bddea9aa87b7510dc2eb413d1a19dfd is the first bad commit

Actually I am not so sure about that.  It appears that sometimes a
bad kernel can boot which might have lead me astray.  That commit
after failing once (assuming I did not make a mistake in the
bisection) is now booting...

It would appear that I accidently marked one step in the
bisection incorrectly but I have now identified the problem
commit and it makes a lot more sense.  The first bad commit is

commit b38d08f3181c5025a7ce84646494cc4748492a3b

     percpu: restructure locking

The commit prior to that one boots reliably but this one fails to
boot a generic kernel.  I'll report it to the linux kernel mail

That's great! Thanks for getting things forward.
