I can reproduce this by changing mtu of eth0 and doing 'skill -1 pppd'. I recovered this only by accident while fiddling with the mtu. It's normally not what you should do I think, but it should not oops I guess. :) The kernel is running with freeswan 1.99. The oops was decoded on the very same kernel. I don't know why it complains about "mismatch on symbol zeroes" in ipsec.o. ksymoops 2.4.5 on i686 2.4.20. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.20/ (default) -m /usr/src/linux/System.map (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options. Warning (compare_maps): mismatch on symbol zeroes , ipsec says d08c9dc0, /lib/modules/2.4.20/kernel/net/ipsec/ipsec.o says d08c9cc0.
