Just disable 64 bit MSIs on all AMD audio PCI ids. Ok. You confirm that this is however good on newer video side right ? Also, is there a known issue that if MSI were once enabled, the chip still shoots them even if we disable them in config space ? When testing my new patch set, I was trying to test the error path when the arch does *not* honor the limitation. The error went back up to the driver as far as I can tell (ie, pci_enable_msi() failed), but the system still got into error state as if the card had tried to shoot an MSI to the wrong address. (I suspect the graphics side) Cheers, Ben. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
