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. [1] https://gitlab.com/qemu-project/qemu/-/issues/624 Signed-off-by: Glenn Washburn <developm...@efficientek.com> --- This is a correction of the commit message from patch #8 of the patch series titled "More test fixes/improvements". The changes remain the same.
