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.
