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. -- ____________________________________________________________________ andrzej sosnowski * raptor@raptor.pl * http://raptor.pl * 0xB71774A2
