    The user enabled it specifically (where it is disabled by default)
    
    ASPM has been crashing e1000(e), which is why I've recently merged a patch to
    disable L1 ASPM for the onboard 82573 nic on those platforms.
    
    this new infrastructure should work in the default configuration - enabling ASPM
    where this system leaves it disabled is expected to give problems unless you know
    what you are doing.
