Forget about differences between the two kernels, in fact with both of them the "ip_conntrack" module is marked as "(deleted)" (not "ipt_state"). lsmod output? Anything in dmesg? What does strace of modprobe show? I thought the problem had vanished because shutting down the machine worked yesterday evening (with iptables-1.2.8-7.1), but I managed to do it again... I'll attach strace, dmesg, lsmod output (dmesg doesn't reveal anything to me, just the occasional cipe messages, iptables log lines...). Created attachment 92904 [details]
gzipped strace of /etc/rc.d/initd.d/iptables stop
made it with:
strace -o $file -Ff -s 512 /etc/init.d/iptables stop
Created attachment 92905 [details]
lsmod output after trying to stop iptables
Created attachment 92906 [details]
dmesg output after trying to stop iptables
the PID of the "guilty" modprobe process ("modprobe -r ip_conntrack_ftp") is 6281, it seems to hang/loop in "delete_module". Hanging in delete_module sounds like a kernel problem. I've seen the same symptoms in 2.4.20-18.7smp. *** Bug 103094 has been marked as a duplicate of this bug. *** The problem doesn't show in kernel-2.4.22-1.2051.nptl -- shall I close the bug or push this back to RHL9 -- it still shows with its kernels. *** This bug has been marked as a duplicate of 103177 *** I've got exactly the same problem on a fedora 3, so I think it's not resolved yet Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
