A recent refactoring of CUDA command code has exposed a bug in OpenBIOS [1] which was causing system powerdown and system reset to fail, thus causing the QEMU instance to hang. This in turn caused the grub-shell command to timeout causing it to return an error code when the test actually completed successfully. Since it could be a while before the patch fixing this issue in OpenBIOS filters down to the average distro, switch to PMU to allow powerdowns and reboots to work as expected.
