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.
