I'd hate to have to look two places just because of ACPI. I agree. I consider the patches Thomas and myself just posted as a temporary workaround (even though we can't say how long this "temporary" will last). Ideally, we should register the I/O ports declared in ACPI OpRegions - just not now as it would break too many drivers. Time we tell how "clean" we manage to go. -- Jean Delvare - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
