Bug#511747: linux-image-2.6.24-etchnhalf.1-amd64: unresponsible for some time, when removing qdisc

[Jindřich Vrba <henly@email.cz>]

Hello,

I don't know how to solve the problem in Linux kernel, but it can by
bypassed with deleting filters and classes before qdiscs.

I'm using something like this:
#tc filter del dev eth0 prio $used_priority #not needed for above sample
classes=$(tc class show dev eth0 | awk '{if (match($3,"^1:1$")==0) print
$3}')
for i in $classes; do
  tc class del dev eth0 classid $i
done
tc qdisc del dev eth0 root
