BTW, the existing kernel | is built with the default "options SCHED_ULE" to make good use of | multiple CPUs, does watchdog work with it? If no one has said yet, kldload ipmi then run watchdogd. ... or compile it into the kernel. This will enable the IPMI HW watchdog. If it triggers, it will appear in the IPMI SEL (ipmitool sel list).
