Revision 1fd684346d41f6be2487c161f60d03a7feb68911 authored by Rafael J. Wysocki on 19 January 2009, 19:57:36 UTC, committed by Jeff Garzik on 27 January 2009, 07:15:51 UTC
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 nx6310 that uses the AHCI driver. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
