Another question: We couldn't reproduce this even with the identical
ARM guest kernel + initrd + command line using qemu-system-arm
compiled for x86-64 host.  This was a bit surprising!  Was that bad
luck or is there some reason why this bug might not be reproducible
except on armv7 host?  (Both cases use -machine accel=tcg).
