Wysocki <rjw@xxxxxxx> > > 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.
