From 5f451fe1ab5d73b987051f0d23c85216c552e163 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 19 Jan 2009 20:59:22 +0100 Subject: [PATCH] SATA PIIX: Blacklist system that spins off disks during ACPI power off 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. Signed-off-by: Rafael J. Wysocki Signed-off-by: Jeff Garzik --- Reading git-format-patch failed
