While we sort out the real technical details, it is OK to go back to pr_debug
please - print_once or some such !
There is lot of useless console noise when we run any networking loads here !

echo 0 >  /proc/sys/kernel/printk

only helps in that it is not printed on console but clobbers dmesg nonetheless !
