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?
