Did you rebuild the kernel and modules? You'll have to do a make
clean followed by make and make modules at least.

Symbols are part of compiled executable code which inform linkers how
to join two or more pieces of compiled code together. E.G. if module
Foo needs to call function bar() which is part of the kernel, the
module loader needs to match the symbol bar in the two pieces of code
and make some adjustments so that the module can successfully call
bar().
If some symbols are unresolved, the two pieces of code can't talk to
each other, which in this case causes the module load attempt to fail.
