hw_enable_irq() and hw_disable_irq() is exactly the same as 
local_irq_enable()/local_irq_disable(), but the output shows while running 
hw_eable_irq() (at that point irq is disabled), the rest of the code is 
blocked, and I don't know why:

output:

What did you expect the output to be?  I assume that you're taking an
interrupt after you enable interrupts?
