pci-quirks: disable MSI on RS400-200 and RS480
MSI doesn't work on RS400-200 and RS480 requiring pci=nomsi kernel boot parameter for ahci to work. This patch disables MSI on those chips. http://thread.gmane.org/gmane.linux.ide/17820 http://thread.gmane.org/gmane.linux.ide/17516 https://bugzilla.novell.com/show_bug.cgi?id=263893 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
