If anyone has any objections, please let us know. --------------------- From: Jay Cliburn 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.
