It shows you the options you can pass. It's bound to be somewhere on-line you can find with Google, if you don't have a working system to read it on (it's from the kernel-doc package). There's various options for ACPI that you might want to try, like forcing it on or off. acpi= [HW,ACPI] Advanced Configuration and Power Interface Format: { force | off | ht | strict | noirq } force -- enable ACPI if default was off off -- disable ACPI if default was on noirq -- do not use ACPI for IRQ routing ht -- run only enough ACPI to enable Hyper Threading strict -- Be less tolerant of platforms that are not strictly ACPI specification compliant. See also Documentation/pm.txt, pci=noacpi -- (This box runs FC5, my others run FC4 & FC6, in case that's important to the thread.) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
