DescriptionI'm experiencing random crashes on machines with these two set of motherboards/cpus

MSI B85M-E45 (MS-7817) - Intel(R) Core(TM) i7-4790K CPU
MSI H170A PC MATE (MS-7971) - Intel(R) Core(TM) i7-6700K CPU

they are are randomly (rarely) crashing

Hardware looks ok (memtest and all stress tests are fine), when the machine crashes it write a dump to /var/crash before doing a cold reboot
