I am a relatively new Linux Hacker (< 6 months). I and a colleague have created a Compact PCI embedded system for which we developed some specific HW. In my device driver, it is possible that the HW will trigger an interrupt for a special case. In this case I want to halt the Linux OS. How can I do this from within my ISR?
