Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org There is a known incompatibility between AMD 76x northbridges and VIA southbridges which makes IO-APIC mode unreliable. (See AMD's errata sheets for details.) The question is: can the Linux kernel run PCI detection before IO-APIC initialisation, so as to prevent IO-APIC mode on mainboards using this configuration? Alternatively we could list known problem boards in the DMI blacklist table, but this is clearly an inferior solution. /Mikael
