I agree with this point. But simply changing the interrupt type in the 
existing logic is not sufficient. Level‑triggered interrupts require 
careful handling in the driver, and with the current implementation I am 
observing issues under system load when using level‑triggered IRQs, as 
also discussed in another thread.
