| |
I've not used ksymoops before, so tell me if I can do something better...
ksymoops 2.4.9 on i686 2.4.21-pre7. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.21-pre7/ (default) -m /usr/src/linux/System.map (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 __io_virt_debug_R__ver___io_virt_debug not found in System.map.
