Subject: [PATCH] Reboot through the BIOS on newer HP laptops
Date: Thu, 24 Nov 2005 05:21:07 +0000 [thread overview]
Message-ID: <20051124052107.GA28070@srcf.ucam.org> (raw)
Newer HP laptops (nc4200, nc6xxx, nc8xxx) hang on reboot with a standard
configuration. Passing reboot=b makes them work. This patch adds a DMI
quirk that defaults them to this mode, and doesn't appear to have any
adverse affects on older HPs.
