This could very easily be a motherboard bug. Many newer motherboards are 
NOT tested properly with ACPI disabled. Your case could easily be due to 
the board's interrupt routing for certain slots/devices being messed up 
when ACPI is not in use. For this reason it's generally not a good idea 
to try to disable ACPI these days.
