However, it is incorrect. The proper hint is in fact: hint.acpi.0.disabled While other ways exist, one way to solve the problem is: To allow the install to boot, at the boot prompt type unset acpi_load Then, after the install, add hint.acpi.0.disabled="1" to /boot/device.hints The way I understand it, setting the above hint to 1 disables acpi. If acpi_load is set and the above hint is not equal to 1, acpi will be loaded. So acpi_load is an abstraction of the hint (less typing). I also prefer that Those With Laptops have to deal with a more difficult install. (Are they a smaller user base?) Either way, the documentation should be probably be updated. If someone with the power to change the docs contacts me I'd be happy to submit an update.
