SATA Sil: 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 nx6325 that uses the sata_sil driver. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
