It is reproducible, happens each time when running "iptables -A INPUT -j DROP", other rules like "iptables -A INPUT -m --state ESTABLISHED,RELATED -p tcp --dport 22 -j ACCEPT" works well tho.

The kernel log dont give any messages before the crash, and since the computer crash hard i cant check for relevant messages after the crash ;)

Im sorry about that glitch, recently compiled 2.6.13-rc5-mm1, but i got a kernel panic at boot, havent looked into that yet, but it might be related to ACPI.
The config for rc4-mm1 and rc5-mm1 is similar.
