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
