    You should run mcelog to decode what the machine checks mean. These do point
    to a hardware problem. Just briefly judging from you description of when
    the MCEs happen I wonder if the power supply is getting maxed out driving all
    of those disks. Either way, use mcelog to find out what the MCEs are first.
