ksymoops 2.4.9 on i686 2.4.25-std-up-alt7. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.25-std-up-alt7/ (default) -m /boot/System.map-2.4.25-std-up-alt7 (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 _nv000173rm , nvidia says c8d84c00, /lib/modules/2.4.25-std-up-alt7/nVidia/nvidia.o says c8d849e0.
