Subject: [Qemu-devel] [PATCH v4 1/7] pc: acpi: fix WindowsXP BSOD when memory hotplug is enabled
Date: Tue, 20 Jan 2015 15:52:26 +0000	[thread overview]
Message-ID: <1421769152-23285-2-git-send-email-imammedo@redhat.com> (raw)
In-Reply-To: <1421769152-23285-1-git-send-email-imammedo@redhat.com>

ACPI parser in XP considers PNP0A06 devices of CPU and
memory hotplug as duplicates. Adding unique _UID
to CPU hotplug device fixes BSOD.
