I suspect this is a known issue with AML code from Toshiba. Their _STA
does not return a value explicitly, but (wrongly) expects the AML
interpreter to get the return value returned by the function _STA is
calling, like
	Method (_STA, ....) {
		AAA(...)
	}
Instead of 
	Method (_STA, ....) {
		Return (AAA(...))
	}

If you can provide ACPI dump data of the machine, that would be helpful
when identifying the cause. Copy the ACPI mailing list and Len.
