This is a problem, L0s and L1 don't work on these adapters, make sure
that the patches to the driver to disable ASPM upon load are in place
and working (by the ASPM value above indicating ASPM Disabled)
The above could be responsible for your issue. If you don't want to
disable ASPM system wide, then you could just make sure to run a recent
kernel with the ASPM patches, or get our e1000.sf.net e1000e driver and
try it, as it will work around the issue whether or not aspm is enabled.
