Hi, I'm thinking of enabling the watchdog on our Dell PowerEdge 2950 / FreeBSD 8.0 amd64, so that it reboots the machine in case of lockups. Right now it doesn't work: # watchdog watchdog: patting the dog: Operation not supported # Looking through the kernel configuration I found two relevant settings: In /sys/conf/NOTES: # # Add software watchdog routines. # options SW_WATCHDOG and in /sys/amd64/conf/NOTES: # # Watchdog routines. # options MP_WATCHDOG Which of them should I rebuild the kernel with? BTW, the existing kernel is built with the default "options SCHED_ULE" to make good use of multiple CPUs, does watchdog work with it? Thanks.
