Just a note that I'm seeing this error on qemu-system-ppc-1.6.0-6.fc21.ppc64, even though this version of qemu seems to include the patch which supposedly fixes this bug. So either this fix is insufficient or something odd is going on with qemu 1.6 as well.

Though we might try to fix other cpu variants as well.
For reasons I don't really understand, qemu-system-ppc64 compiled from git works fine.
