Do these tests have an early serial console enabled?  I want to confirm
that the failure is very early in boot before or just as we reach C code.

If you don't have an early console we could be failing late in the process just
not have visibility.

If you have a serial console to add a little bit of instrumentation super duper early.
Although looking at the generated objects might be just as interesting.
