gcc version 2.95.4 20011002 (Debian prerelease)
I'm not sure about what triggers it but looks like it happens every time
at boot time.
ksymoops 2.4.5 on i686 2.5.44. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.44/ (default)
-m /boot/System.map-2.5.44 (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_ksyms_lsmod): module parport_pc is in lsmod but not in ksyms, probably no symbols exported
