-Subject: [PATCH] SATA PIIX: Blacklist system that spins off disks during ACPI power off
-References: bnc#441721
-
-Some notebooks from HP have the problem that their BIOSes attempt to
-spin down hard drives before entering ACPI system states S4 and S5.
-This leads to a yo-yo effect during system power-off shutdown and the
-last phase of hibernation when the disk is first spun down by the
-kernel and then almost immediately turned on and off by the BIOS.
-This, in turn, may result in shortening the disk's life times.
-
-To prevent this from happening we can blacklist the affected systems
-using DMI information.
-
-Blacklist HP 2510p that uses the ata_piix driver.
