I'm not sure that noacpi is an option...perhaps you mean noacpi=1

you can also boot with the param 'acpi=off' but that is what is known as
the 'big hammer'

Okay, I've asked that question a dozen times on here, what's the option
to shut off acpi. I've been told 'noacpi' every time. Not 'noacpi=1'.
I've also been told acpi=off doesn't work/isn't used any more.


Used to I'd add noacpi,acpi=off to my kernel boot line. Then I was told
acpi=off wasn't used (or whatever). So, now I'm really confused.

I'm no expert - that's why I provided the link. acpi=off clearly is a
valid option (they label it the big hammer)

You may need to pass additional options, or better yet disable at the BIOS. More info on this page:

The most obvious advice would be to install the kernel-doc packages, and
read the kernel-parameters.txt file in there. It should reflect what
options the current kernel supports.

less /usr/share/doc/kernel-doc-*/Documentation/kernel-parameters.txt
(then type /acpi while reading it, and hitting enter to find the next
mention of acpi).

Supposedly, acpi=off should be accepted, according to the documentation.
Depending on your problem, there might be other parameters that might be
of use to you.
