Shortly after that the system locks up solid. Maybe, this is due to another attempt at halving (below the minimum speed listed in freq_levels). >How-To-Repeat: powerd >Fix: The proper fix would require figuring out, what exactly is wrong. A work-around would simply add the minimum allowed speed to the command-line options for powerd, so that the administrator could set that up. This would be handy even on a non-hanging system, where the admin may want to disallow it to go below certain speed for performance reasons. >Release-Note: >Audit-Trail: >Unformatted:
