Reset adapter
Server is a HP Proliant DL120G6 with 2 integrated gigabit nic which uses
e1000e driver for "Intel Corporation 82574L Gigabit Network Connection".
This happened in kernel 3.2.0-60-lowlatency. Before that i tried
3.2.0-33-generic-pae and similar thing happened. So i'm quite sure it exists in
all kernel versions.
I tried to manually compile e1000e driver from sourceforge but that just did
work terribly (didn't crash just didn't work well).
We use this machine as pppoe concetrator and important thing is that this
crash never happened on the interface that is configured as link (have an ip)
but only on interface that is setup as pppoe server (kernel mode) so it maybe
related to this.
When this happens eth0 interface is down and as you can imagine all pppoe
connections are lost while eth1 works just normally.
I am quite aware this will be very hard to reproduce and this doesn't happen
right away - server can work for months before crashing.
