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 ;) > You are reporting this against 2.6.13-rc4-mm1, but are attaching a > .config of 2.6.13-rc5-mm1. Which kernels are affected, and which are > not? 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? Havent tried this yet, but ill do it right away. > Please send the output of ./scripts/ver_linux . If some fields are empty or look unusual you may have an old version.

Could be related to the refcnt underflow with conntrack event notifications enabled. If you have CONFIG_IP_NF_CONNTRACK_EVENTS enabled please try this patch. [-- Attachment #2: x --] [-- Type: text/plain, Size: 10692 bytes --] [NETFILTER]: Fix multiple problems with the conntrack event cache refcnt underflow: the reference count is decremented when a conntrack entry is removed from the hash but it is not incremented when entering new entries. missing protection of process context against softirq context: all cache operations need to locally disable softirqs to avoid races. Additionally the event cache can't be initialized when a packet enteres the conntrack code but needs to be initialized whenever we cache an event and the stored conntrack entry doesn't match the current one. incorrect flushing of the event cache in ip_ct_iterate_cleanup: without real locking we can't flush the cache for different CPUs without incurring races. The cache for different CPUs can only be flushed when no packets are going through the code. ip_ct_iterate_cleanup doesn't need to drop all references, so flushing is moved to the cleanup path.
