Subject: 2.4.21 oops

---

Hi.

Kernel makes an oops while executing the following script:

#!/bin/sh
for IP in `/usr/bin/seq 3 500`; do
ip addr add 3ffe:80ee:c1d::$IP/48 dev eth0
ip addr add 3ffe:80ee:c1d::a:$IP/48 dev eth0
done

Result:
kernel BUG sched.c 564!
(sorry for incomplete oops message)

Tested on:
debian 2.4.21
debian/redhat 2.4.21-grsec 1.9.10
redhat 2.4.21-uv2-grsec 1.9.10

This script with 2.4.20 working fine.
