That looks more like 0.0.2 than 0.0.3.. Anyway, could you please run the
error message through ksymoops or manually resolve the back trace and
EIP addresses. I would need to know the function names to make this
report more usable.

A quick guess based on this:

That does not look good.. Are you sure that your hostap.o and
hostap_plx.o are from matching source code and compilation options? That
error could occur if they are, e.g., from different driver versions or
are compiled with different options, etc.
