Matthew, You are right, of course, we're not doing something right if a new machine needs this workaround. However, we don't yet know what we're not doing right:-) Until we figure that out, the blacklist is a practical way forward. There have been several cases in the past where we grew a blacklist -- some of them quite large, before we figured out what bug-compatibility magic we needed in order to delete the blacklist. I'm hopeful the same story will play out here. applied. thanks, -Len -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
