Dear Kernel Hackers

I get following oops at boot up after kudzu is trying to load the 
parport driver for my Canon parport printer.  Attached you will find my 
.config file and the dmesg. Kernel was compiled with GCC 3.4.1.

Now with ksymoops:

ksymoops 2.4.9 on i686 2.6.8.1.  Options used
     -V (default)
     -k /proc/kallsyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.8.1/ (default)
     -m /boot/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 (read_ksyms): no kernel symbols in ksyms, is /proc/kallsyms a 
valid ksyms file?
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
