Ah my understanding was that it applied to NF3 and possible NF4 too.

Yes it was because NF5 needed it to be disabled. Anyways if I can get a list of PCI-IDs of chipsets where the reference BIOS had this issue it can be narrowed to those. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
