Hi, I am working on IPMI watchdog implementation . The problem that I am facing is that in case of improper system shutdown or powerfail the watchdog keeps running and the next time system boots up , BIOS complains of FRB2 timeout and fails one of the CPU's ( Working on SMP system ) . My idea is to handle NMI generated by abruptly pushing power button and disabling the timer in the routine. Can we have a handlers for NMI ?? I am not very sure what is happening inside the kernel when NMI is delivered . Please provide me some inputs. Dip
