[etherlab-users] e1000e driver still not working with 3.2 kernel with latest stable-1.5 branch?

Tue Feb 5 06:26:43 CET 2013

Hi Jürgen & Daniel,

I have a fix for the first issue in my local copy of the driver (see my post
to the dev list on 25 October for specific details).  I have seen the second
issue but not chased down a fix for it yet.

Also I just noticed that Florian updated the drivers on 4 January (posted in
response to my message; I havent checked whether it includes the same fix
or not).  I havent had a chance to test the new version myself yet but
maybe it will help in your case too?

Regards,

Gavin Lambert

Hello Daniel,

I am using this combination for a while now, with 32- and 64-bit versions of
the 3.2er Debian RT-Kernel. If there is a EtherCAT device connected to the
computer, the driver works fine.
There are two issues in this driver version, if there are no EtherCAT
devices connected. The first, the one you mentioned here, is when the
EtherCAT Master starts up with no device connected, then the network-adapter
is continously reseted until a device is connected. It may hang the computer
if no device is connected for a while.
The second issue is that when the link is plugged off, the link state is not
updated. Unfortunately, I did not have time yet to correct these issues.

Greetings,
Jürgen Kunz

Has anyone else gotten this combination of driver and kernel to work?

Here's the /var/log/messages output when I start the ethercat master:

And the reset adapter message occurs every 2 seconds until I stop the
ethercat master.
