The MCE's are the processors way of saying something is extremely wrong that it can detect. This typically will cause a panic though not causing a reboot. OTH, If your hardware also has support for a watchdog then shortly after the panic a reboot would occur. I'm not saying that this is what is actually happening, but just that along the lines of what has been said thus far, this would make sense. If indeed this is the case, maybe the panic output is in /var/log/messages. Cheers...james > >
