HP DL585 G2 Machine Check Exception

This problem has been seen for awhile on all flavors of hardware: CPU X: Machine Check Exception: 0000000000000004. In can come from a kernel recompile after new drivers have or havenot been upgraded. Upgrading OS on older hardware can cause this exception throw. At any rate your system is now rendered unstable and probably should be returned to the last good known configuration - so goes the old addage - "upgrade or die!"
