[RTnet-users] Problem with e1000e driver

[Wojciech D. <woj...@gm...>]

Dear all,

I am experiencing some problems using the rt_e1000e driver for RTnet.

What I am doing is pretty simple, however not everything is working as
it supposed to. After I start the rtnet service I'm keep getting such
communicates from syslog:

TDMA: Failed to transmit sync frame!

and occasionally:

rt_e1000e: Reset adapter

After quite long time (at least few minutes)
the driver manages to establish the connection
and then everything is working as it should.

As my set-up I'm using mother board with those ethernet devices:

00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network 
Connection (rev 04)
04:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network 
Connection
a 8-port switch
a dedicated device bases on a microcontroller running RTnet.

As I described before I was able to establish the transmission and
then everything is working as it should. The time needed for
establishing the connection is however unacceptable.

Also I have tried repeating the same scenario but this time
only using the switch and everything is as previous.
Moreover, I tested this on different machines and I'm experiencing
the same problem.

I've found this on mailing list:

encouraged I've tried it by editing rtnet script by adding a substantial 
delay
of few seconds after all the drivers were loaded. Unfortunately,
that didn't solved the problem.

Different approach was to try the patch for the newest version
for e1000e driver and this one also didn't solve the problem.

Best regards,
