Hi, I'd like to implement a driver for an PC-like embedded system. The watchdog timer can generate SMI, NMI and IRQ's. One of them I would like for reboot, if an app or a driver hangs up. How can I implement an ISR for a NMI, which resets the system ? Franz - Kernelnewbies: Help each other learn about the Linux kernel.
