typo in handbook 11.16.3.2 System Hangs

[doug]

Thanks to all. BTW the handbook is great. I started with 3.5 and it (the
handbook) just gets better and better.

I read that paragraph to mean turning off ACPI and was not aware of APIC. I was
told when debugging a sound card problem that I should turn off ACPI because my
laptop was getting error messages. My understanding of this advice was that ACPI
along with an older BIOS could cause interupt problems. If this is true perhaps
both should be mentioned.
