[LARTC] is this a bug?

[Folke Aeon]

hi, all

i met another question.

i do the following on my linux,

tc qdisc add dev eth1 handle 1:0 root dsmark indices 64
tc class change dev eth1 classid 1:11 dsmark mask 0x3 value 0x28
tc class change dev eth1 classid 1:21 dsmark mask 0x3 value 0x48
tc filter add dev eth1 parent 1:0 protocol all prio 1 handle 2 \
             tcindex classid 1:11
tc filter add dev eth1 parent 1:0 protocol all prio 1 handle 1 \
             tcindex classid 1:21

but when i type :
  "tc qdisc del dev eth1 root" and press enter,
my linux died: not only my keyboard is locked, but
everything is locked too, all i can do is to press
'reset' KEY to reboot my computer.

does anyone else has met this before?

Which kernel ... ? SMP or not ? CONFIG_PREEMPT set ?

At least 2.5.44, neither SMP not preempt, didn't do anything
funny when I tried this.

  i turned the SMP off , and everything is ok now. :)

  i do have a single CPU machine and i was so careless
that i did not notice that option. :)

good. :)
