could you send the patch for that? Is it upstream already?

It's indeed an IrDA bug (though mainly visible under rt-preempt) and the patch has been sent to the maintainer and to stable.

user.warn kernel: Neighbour table overflow.

hm, i havent seen this one yet.

it comes from net/ipv4/route.c::rt_intern_hash()... That's all I can say so far. Any debug ideas? Could you try on any your rt-test system just a loop like

while true; do
	ifdown eth0
	ifup eth0
	ping -c 1 host
done

or similar. Or, better yet with starting / stopping pppd?

Thanks
