Panic message says that MADT is related to ACPI, not APIC. The, the second paragraph talks acpi0, then the last paragraph talks disable it via setting hint.apic.0.disabled="1" Nowhere in the entire web page says about hint.acpi.0.disabled variable. This is the part confuse me to believe that this may be the typo. If both hint.apic.0.disabled and hint.acpi.0.disabled exist, a clear introdution should be placed at front (top of the page) to illustrate what difference they are, and where they should be used for.
