Subject: [PATCH] prevent acpi from rerouting SCI interrupt
Date: Thu, 24 Dec 2009 14:37:16 +0200 [thread overview]
Message-ID: <20091224123716.GA5691@redhat.com> (raw)
SCI interrupt in piix4 chipset is hardwired to gsi 9, but we allow it
to be reconfigured by acpi. Fix this by providing fixed gsi for
PCI device 1 pin 0.
