Problem is, if the serial device on /dev/ttyS0 is receiving data and generating ints, this serial servicing tsr crashes during its init. But if the port is quiet it starts fine. So, I ask for suggestions on ways to temporarily disable irq 4 interrupts from happening, until after this tsr starts ???
