A fixed BIOS will not have a bogus IRQ2->pin-2 mapping, so the acpi_skip_timer_override workaround would not find an entry to ignore, and would become a NOP. So if 1. all nforce2 chipsets have timer connected to pin0 2. we can safely discover we're on nforce2 early enough, like andi did on x86_64 then we could apply the workaround automatically always w/o any harm. -Len - 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/
