I followed the steps on the power management test day instructions. The first call e.g. "tuned-adm laptop-battery-powersave" worked. However all subsequent uses of tuned-adm, e.g. "tuned-adm spindown-disk", hung on "Stopping ktune (via systemctl)". I waited a minute, hit Ctrl-C, and it said "Stopping ktune (via systemctl)" again but this time said "[OK]" then "Switching to profile 'spindown-disk'" and then hung on "Starting ktune (via systemctl)". After Ctrl-C I heard my speaker click and it hung again on "Starting ktune (via systemctl)". Waiting another minute and pressin Ctrl-C again drops me back to the command prompt.
