== Faster resume from power suspend in systems with hard disks ==

Resuming a system from suspend used to take a long time in systems with traditional hard disks, because the system blocks the resume process until the hard disk finish powering up. In this release, commands are sent to the hard disk asynchronously, so the entire resuming process isn't paused by the hard disk. The end result is that systems with hard disks will resume several seconds faster with this Linux release.
