2.4.21-rc7-ac1 only has the CPUFreq patches applied, courtesy of Bill
Nottingham. There is no FreeS/WAN patches applied to it.

I have just run another compile of 2.4.22-pre3, this time nothing else
applied. The oopses is as follows.

ksymoops 2.4.8 on i686 2.4.21-rc7-ac1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-rc7-ac1/ (default)
     -m /boot/System.map-2.4.21-rc7-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.
