Despite finding the obvious error earlier today I've still been trying to get
this to work.

I had to make some slight modifications to use the 0-day cross compile build
and my local qemu build.  But those were pretty minor modifications.  I'm
running on x86_64 host.

With those slight mods to the scripts I get the following error even without my
patch set on 5.7-rc4.  I have 1 cpu pegged at 100% while it is running...  Is
there anything I can do to get more debug output?  Perhaps I just need to let
it run longer?

Thanks,
Ira
