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.
Any other suggestions?
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.

Hi,
Sorry for the delay, been off the past 4 days.
I'll see how closely I can narrow down where the fault is. I have been inserting
very early printk's to track how far into the startup it gets before bailing.
Thanks,
Mike
