Somehow, the xenomai-help mailing list does not receive your mails. So,
I am resending your mail to the list.


Hi Gilles, Hi list,

nearly everything is working fine. I rebuild the kernel again without the
given options and it seems to work.
Even the latencies look quite much better. There is only one problem left
that bothers me.

Every time I load the rt_eepro100 for my real-time device I get the
message:

[   95.753152]   *** Receiver lock-up bug detected ***
[   95.753154]   Your device may not work reliably!

and sometimes the systems hangs (and can not be woken up) at this point.

I know that this is a hint for a irq problem but I don't know where this
should be.
My eth0 device (irq6) is not sharing this irq with an other deveice.

IRQs after boot:

         CPU0
  0:         40    XT-PIC-XT        timer
  1:         52    XT-PIC-XT        i8042
  2:          0    XT-PIC-XT        cascade
