That's very interesting and mysterious indeed!

Let me summarize the situation for clarity. Debian Buster can install on
Arndale correctly. It builds on target Xen and Linux, based on the
provided branches. The binaries produced by the build of Xen and Linux
fail to boot correctly on Arndale, even though the same version of Linux
and Xen have been tested successfully previously on Arndale as part of
regular OSSTest runs. Yeah, I cannot make any sense of that :-/

I assume that the device tree used is still also the same?
