If the PPS GPIO is exposed to a signal with high frequency changes, a lot of interrupts are scheduled and the handling of these calls can worst-case starve flight critical processes leading to a loss of control. Since PPS is not flight critical, we now give up the PPS functionality and stop the interrupts to prevent the starvation of other processes.
