      11.16.3.2 System Hangs (temporary or permanent)

It talks about "... correctness of the APIC (MADT) table", which seems 
not matching
the panic message above. 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.

Thanks,
