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. > Are there any messages that might give a hint where to search for the > problem? 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 ;) =20 > You are reporting this against 2.6.13-rc4-mm1, but are attaching a > .config of 2.6.13-rc5-mm1.

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. > Does it still happen if you compile your kernel with preemption > disabled?

Compare to the current minimal requirements in Documentation/Changes.
