== Comment: #2 - VASANT HEGDE <hegdevasant@xxxxxxxxxx> -  ==
Below upstream patch fixes this issue..I believe this will apply cleanly on top of Ubuntu 14.04.04 kernel.

    powerpc/pseries: Limit EPOW reset event warnings
    
    Kernel prints respective warnings about various EPOW events for
    user information/action after parsing EPOW interrupts. At times
    below EPOW reset event warning is seen to be flooding kernel log
    over a period of time.
