I just happened to notice that everyone who had the problem seemed to be using iptables. just to recap what the problem is: kernel 2.4.2[10] maybe even .19, etc SMP deadlock. systems still responds to ping, iptables logs still scroll along on the console. but nothing else. please see my post with ksymoops output of sysrq+T : http://marc.theaimsgroup.com/?l=linux-kernel&m=105821579624140&w=2 however, the deadlock happened when the system was under heavy disk IO. all filesytems are raid1, ext3. here are my modules: [mh@zara mh]$ /sbin/lsmod Module Size Used by Not tainted ip_conntrack_ftp 5424 0 (unused) 8139too 17832 1 mii 4124 0 [8139too] e100 55236 1 ipt_REJECT 4024 2 (autoclean) ipt_state 1048 34 (autoclean) ipt_limit 1688 2 (autoclean) ipt_LOG 4248 4 (autoclean) iptable_nat 22872 0 (autoclean) (unused) ip_conntrack 29896 3 (autoclean) [ip_conntrack_ftp ipt_state iptable_nat] iptable_filter 2412 1 (autoclean) ip_tables 15672 8 [ipt_REJECT ipt_state ipt_limit ipt_LOG iptable_nat iptable_filter] keybdev 2944 0 (unused) mousedev 5688 0 (unused) hid 16296 0 (unused) input 6144 0 [keybdev mousedev hid] usbcore 80704 1 [hid] ext3 76096 3 jbd 65904 3 [ext3] raid1 16108 4 -m - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
