The codepath you see in that backtrace is only hit during load or removal of the 'ip_conntrack' module. While this certainly still should not oops, your description of 'not doing anything but IMAP reading' is certainly not true. Could you please describe what actually happened when that bug happened? It looks to me that you were unloading ip_conntrack_netlink.ko followed by ip_conntrack.ko. > Generic details such as .config is at http://www.reub.net/files/kernel/ You don't have permission to access /files/kernel/ on this server. -- - Harald Welte <[EMAIL PROTECTED]> http://netfilter.org/ ============================================================================ "Fragmentation is like classful addressing -- an interesting early architectural error that shows how much experimentation was going on while IP was being designed." -- Paul Vixie
