From 184b812f7da6726d7ea4ca409c7a8762ff6c6df6 Mon Sep 17 00:00:00 2001 From: Jay Cliburn <jacliburn@bellsouth.net> Date: Sat, 26 May 2007 17:01:04 -0500 Subject: [PATCH] PCI: quirk disable MSI on via vt3351 The Via VT3351 APIC does not play well with MSI and unleashes a flood of APIC errors when MSI is used to deliver interrupts. The problem was recently exposed when the atl1 network device driver, which enables MSI by default, stimulated APIC errors on an Asus M2V mainboard, which employs the Via VT3351. See http://bugzilla.kernel.org/show_bug.cgi?id=8472 for additional details on this bug.
