Subject: 3.18.2 crashes on Supermicro X10DRL-i motherboard

I have a system with a Supermicro X10DRL-i motherboard and dual Xeon E5-2620 
processors.   The system runs fine under 3.17.7, but crashes under 3.18.1 and 
3.18.2.   Below is the crash dump and kernel configuration file.   Does anyone 
have any suggestions short of kernel bisecting?  Thanks.
