ksymoops 2.4.3 on i686 2.5.5-dj2. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.5.5-dj2/ (default) -m /boot/System.map-2.5.5-dj2 (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): ksyms_base symbol idle_cpu_R__ver_idle_cpu not found in System.map. Ignoring ksyms_base entry Warning (compare_maps): ksyms_base symbol vmalloc_to_page_R__ver_vmalloc_to_page not found in System.map.
