FATAL: Error inserting mISDN_dsp (/lib/modules/3.2.0-24-generic-pae/extra/mISDN_dsp.ko): Unknown symbol in module, or unknown parameter (see dmesg)

This means your modules do not match the kernel or associated libraries as the kernel sees symbols it has no idea how to interpret. You need to clear out all the mISDN modules and start recompiling/installing again to make sure you have the matched modules being loaded.
