I had this problem, once.  I ran into it because uClibc has
smaller default stdio buffer sizes, and the proc read function
in the hostap driver does not support reads from seeks greater
than 0.  Therefore, it aborts when it goes to read the second
chunk from the procfile.

If this is the same problem you're having, especially if you're
accessing it with uClibc stdio, you should be able to fix it by
giving it a larger buffer.  Probably something like setbuffer()
would do this.
