Hi everyone,
I am experiencing problems regarding realtek r8169. My system is flooded
with:

I am running IgH EtherCAT 1.5.2 on top of Linux 3.14.15 using the
real-time co-kernel Xenomai 2.6.5. The error occurs when the ec_r8169 is
loaded and the master is connected with different products that I have
tested:
Sanyo Sansmotion R
Maxon EPOS3
However, the error does not occur for the following servo drives though:
LS Mecapion L7
Panasonic
Does anyone have an idea what seem to be the problem?
