WebFeb 6, 2024 · That leaves IRQ 0, which is the system timer, and which you can't do anything about, and IRQ 177, which is tied to your b4xxp driver. My guess is that IRQ 177 would be your culprit. If this is causing a problem, and you would like to change the behavior your see, try: disabling the software that uses that card, and see if the interrupts decrease.
