This is caused by an erroneous write of CIR_INTR_MOUSE_IRQ_BIT to ACPI control register. According to datasheet the write enables mouse power management event interrupts which will probably have ill effects if the motherboard has only one PS/2 port with keyboard in it. The cir hardware does not need mouse interrupts to function and should not touch them. This patch removes the illegal writes and registry definitions.
