Hi all,
I have compiled a kernel 2.6.28.10 +  xenomai2.5.1 and successfully booted on s3c2440 based board with DM9000, but ethernet comunication doesn't work and I see the following messagge; when i remove the Kernel Features->interrupt pipeline support, the ethernet work well.Can someone help me?

First, an unrelated question: does 2.6.30 boot? We received two reports
about people not being able to boot an I-pipe patched kernel on s3c24xx,
so, I am curious to know whether it could be a problem with the I-pipe
patch, or something else.

Now, about your issue, could you try and run:
cat /proc/interrupts
after observing the bug? What you should be looking for is whether the
ethernet driver interrupts counter increments or not.
