Here (eventually) is the output from ksymoops for the Oops on loading
the Creative joypad module. I'll try Vojtech Pavlik's "quick fix" for
the Gravis driver later to see if that changes anything.
Andrew Gormanly
ksymoops 0.7c on i586 2.2.14. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.14/ (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.
Warning (compare_ksyms_lsmod): module joy-creative is in lsmod but not
in ksyms, probably no symbols exported
