I even went as far as replacing the motherboard. At first, I thought I had bad RAM -- but even with known-good RAM, I still have random reboots. As with your situation, there are no apparent patterns. Regarding mbmon, I had to compile it without SMB4 support to get it to work. My MB is an Intel D845PESV (desktop board). -- Glen Barber
