I search all scientific linux mailing list.
It seems to be similar problems what we have.
Should I upgrade all SL 4.0 default kernel to new one ?

Distribution:
Scientific Linux SL Release 4.0 (Beryllium)
CPU: AMD 1.8 opteron (Single)
iptables v1.2.11 & 2.6.9-5.0.5.ELsmp Scientific Linux SL Release 4.0 (Beryllium)
iptables version:
iptables -V
iptables v1.2.11
kernel version:
2.6.9-5.0.5.ELsmp
It is hanging when I do
/sbin/iptables -A INPUT -p ALL -i lo -s 127.0.0.1 -j ACCEPT
After yum update,
kernel upgrade to 2.6.9-11.ELsmp then ok
