I did a grep thru the entire kernel sources and didn't see that message
anywhere. The only thing I can think of is that you have a local driver
that is producing it. I suggest that next time it happens you enter the
debugger with a control-alt-scroll_lock, and put a breakpoint at
printf. You should then be able to get a traceback and see where the
message is coming from.

The routing control field (rcf) is an unsigned short which is a group of
bitfields. Here's my declaration

	struct rcf {
		unsigned broadcast : 3;	/* broad- or uni-cast, warning! */
		unsigned bridges   : 5; /* hop count, we use 8 as max */
		unsigned direction : 1; /* which way to read the route */
		unsigned length    : 3; /* mtu, we use ether mtu for sanity */
		unsigned reserved  : 5; /* reserved */
	} 

My guess is that someone has stuck a printf in the lan_output() routine,
or in the lan_output_llc() routine (somewhere between lines 1000 and 1200),
although there are a few other points in the driver where the rcf is being
manipulated, these seem the likely spots for your mystery printf.
