Bug#858125: e1000: ethernet interface hangs occasionally, kernel reports hang
Here is the dmesg output from just this afternoon:
[Mar18 12:40] e1000e 0000:03:00.0 eth0: Reset adapter unexpectedly
[ +3.891401] e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx

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?
