Here is the dmesg output from just this afternoon:

	[Mar18 12:40] e1000e 0000:03:00.0 eth0: Reset adapter unexpectedly

which is pretty extreme.  Eight resets in five hours!  This is a home
server (momjian.us) so it isn't like it is pushing huge amounts of data
or overloaded.

I did so much research on this before reporting it because this is
common hardware (SuperMicro) and Intel PRO/1000 ethernet adaptors, which
are also popular.   There must be something odd about my server, but I
have no idea what it is.  Also, if I buy a dual PCI-E adaptor, it will
also be an Intel PRO/1000.  Will I get the same errors on that?
