Hey, @xnox.
Can you try the attached patch and see if that works out? It's possible
that other functions need to be marked notrace.

The alternative theory here is that this is always breaking at

Looking at the crashing address (by doing objdump on the vmlinux from
the ddeb), it lands on the middle of an instruction.

Is there a way to attach gdb over jtag to unmatched board whilst it is
attempting to boot?
Is there a way to analyze the vmlinuz image to figure

I am failing to reliably reproduce this issue.
At first I have experienced this too. When I tried to bisect it and install
multiple kernel abis they are all booting fine.
So I was able to fail booting 1014 1015 1016 abis. And then they started
