CRASH during boot 3.16.3+

[Udo van den Heuvel <udovdh@xs4all.nl>]

Hello,

3.16.2 boots and works fine.
Kernels 3.16.3 and newer crash very early during boot. (did not yet try
3.17)

The problem:
During the first few seconds of bootup the kernel gets into some sort of
loop and rapidly prints loads of register-like things and then a load of
rubbish.
I did `make clean` and then a rebuild etc but this did not help.

How can I capture the logging to find the point where things go wrong?
How can I find out what is wrong?
How can this problem be fixed?

Please post your insights.

Kind regards,
Udo
