Just did a distclean. Now the inluce/linux/modules/netsym.ver has the
fdbIoSwitchHook version info. 

Recompiled the module. Did a nm on the module, and saw the version info
for the symbol. But when I dod insmod, it still complained about
unresolved symbol fdbIoSwitchHook.

It seems now the version is different between the kernel and the module.
Should I wait for the bzImage compilation to complete and install the
new kernel?


Thanks a lot,
Jason
