Synopsis: [ata] Powerup of sleeping IDE drives causes system reboot. State-Changed-From-To: open->closed State-Changed-By: brucec State-Changed-When: Fri Mar 12 23:26:26 UTC 2010 State-Changed-Why: HDD APM can cause kernel panics and hangs depending on the ata controller because the driver wasn't designed to have disks being spun down. Unfortunately the only workaround is to not run ataidle. In 8.0 and newer there's a new cam based driver that has built-in support for power management that should be more reliable.
