Hello Gilles,
Thanks for the advice.
Yes, I have problem with sharing the IRQ 11.
my questions are:
How can I set the rteth0 to a known not sharing IRQ in the system?
How can I pass a known IRQ from RTnet to the Xenomai xnintr_shirq_handler?
I tried to fix the IRQ from "network configuration" but it didn't help. I also tried to set up the system BIOS but it did not have IRQ configuration.
The Realtek NICs are using PCI bus.
Thanks,
Dennis

There are several reasons why this can happen. One reason is a bug in
the drivers interrupt handler, which returns RTDM_IRQ_NONE whereas it
should not. Another reason is that the IRQs 10 and 11 are shared
between the ethernet driver and non real-time drivers. This can not
work.
