Subject: [PATCH] Set bit 1 in disabled processor's _STA
Date: Fri, 15 May 2009 08:14:43 -0400	[thread overview]
Message-ID: <1242389683-12967-1-git-send-email-glommer@redhat.com> (raw)

This patch sets bits 1 in disabled processor's _STA.
According to the ACPI spec, this bit means:
 "Set if the device is enabled and decoding its resources."

Without it, Windows 2008 device manager shows the processors
as malfunctioning hardware.
