Hmm while playing with the device tree append patch, decompress_kernel
trashes the first 16 bytes of the device tree data. Now I wonder if these
issues are related..

Aaro, you mentioned to me that reverting commit 
6d7d0ae51574943bf571d269da3243257a2d15db helps too?

With the device tree append patch reverting commit
d239b1dc093d551046a909920b5310c1d1e308c1 does not help, and reverting
6d7d0ae51574943bf571d269da3243257a2d15db requires some manual merging..

Anyways, that might be another way to reproduce the problem if these
issues are related.
