ksymoops 2.4.5 on i686 2.4.23. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.23/ (default) -m /boot/System.map-2.4.23 (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. Error (expand_objects): cannot stat(/lib/ext3.o) for ext3 Error (expand_objects): cannot stat(/lib/jbd.o) for jbd Warning (map_ksym_to_module): cannot match loaded module ext3 to a unique module object. Trace may not be reliable.
