From d7959916026aaae60e1878ae33c7503b2cc4471d Mon Sep 17 00:00:00 2001 From: Maxime Bizon Date: Mon, 29 Oct 2012 14:40:19 +0100 Subject: x86/ce4100: Fix reboot by forcing the reboot method to be KBD The default reboot is via ACPI for this platform, and the CEFDK bootloader actually supports this, but will issue a system power off instead of a real reboot. Setting the reboot method to be KBD instead of ACPI ensures proper system reboot.
