From b0aedb04eae79372fbe101d98513773d6b89935d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bruno=20Pr=C3=A9mont?= Date: Wed, 22 Apr 2009 20:33:41 +0200 Subject: ide: Stop disks on reboot for laptop which cuts power MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit My laptop (Acer Travelmate 660) always cuts the power when rebooting which causes the disk to emergency-park it's head. Add a dmi check to stop disk as for shutdown on this laptop.
