About two months ago it started hanging. It's completly freezing machine (no ooops. First of all when it's booting few messages like this appears on screen: NF_IP_ASSERT: ip_conntrack_core.c:1128(ip_conntrack_alter_reply) I suppose it's showing before firewall script load rules (simple nat). After that somtimes it's working very long, sometimes it's freezing after few seconds. One time I've logged this message before it freezes: kernel: LIST_DELETE: ip_conntrack_core.c:302 `&ct->tuplehash [IP_CT_DIR_REPLY]'(decb6084) not in &ip_conntrack_hash[hr]. Components that has been already replaced: - computer hardware (twice to a new one) - fast ethernet cards (tried with intel, realtek and 3com) - fresh system (debian sarge) - switches Router and switches are connected to UPS (dedicated, also replaced). This is a vanilla kernel 2.4.31, problem also exist with kernels: 2.4.30, 2.4.29. I tried also with grsecuriry(hoping it could help) patch, but it wasn't. If you have any idea what I can try to fix please let me know. Thank you for your time.
