Subject: [PATCH 0/2] Stop disks on reboot for laptop which cuts power

Hi,

During shutdown (power off) the disks are stopped gracefully thus the
stopping is skipped for reboot case.

On my Acer Travelmate 660 reboot is more like power-off as it cuts all
power during reboot which currently causes the disk to emergency-park
its head (noisy and shortens disk life).

This patch series adds a DMI-based check to ide-gd and sd to still
stop the disks for affected laptop during reboot.

Has been compile an run-tested with libata and just compile-tested for
ide.
