May be we should consider this behaviour broken anyway, since there are other features that will never be available, such as TSC. So why not simply disable ACPI for 386 ? > Inline func please.

But I'm too lazy this evening for something which has too few chances of being the definitive solution :-) Cheers, willy - 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/
