No, Only comment the test, you must absolutely leave the __hard_irq_disable() call ! That's the whole point of the test, make sure we unconditionally disable to see if that fixes the problem, in which case that will tell us that we somewhere accidentally leave irq_happened set to 0x01 while irqs are hard enabled.
