ksymoops 2.4.0 on i686 2.4.19-pre10. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.19-pre10/ (default) -m /boot/System.map-2.4.19-pre10 (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. No modules in ksyms, skipping objects Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file? Warning (compare_maps): ksyms_base symbol vmalloc_to_page_R__ver_vmalloc_to_page not found in System.map.
