I was able to reproduce this on another board with appended dtb,
looks like uncompress happens fine but then nothing. Looking at
System.map the u-boot alignment warning Merlijn posted, pc is
somewhere very early in the kernel.

I can easily reproduce the issue now if you have something in mind
to try.
