Subject: hard hang through qdisc



I just managed to hang a 2.6.24 (+ some non network patches) kernel 
with the following (non sensical) command

tc qdisc add dev eth0 root tbf rate 1000 burst 10 limit 100

No oops or anything just hangs. While I understand root can
do bad things just hanging like this seems a little extreme.
