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. -Joachim - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
