ksymoops 2.4.4 on i686 2.5.61-ac1. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.5.61-ac1/ (default) -m /boot/System.map-2.5.61-ac1 (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 (regular_file): read_ksyms stat /proc/ksyms failed No modules in ksyms, skipping objects No ksyms, skipping lsmod activating NMI Watchdog ... done. testing NMI watchdog ... OK.
