I tried to use your code but after about 20 minutes it still worked so I gave 
up. After I kill it, there were some warnings

9: In rq.fit.sfn(D, y, rhs = a) :
  tiny diagonals replaced with Inf when calling blkfct

but I cannot decipher what it is about.

Your code is quite complicated and you hardly get any answer if you do not 
specify better where are the errors and what they tell, especially if others 
observe the same (long) calculation.

Use traceback() and/or debug() functions to see what is going on.
You also maybe could try to test your functions on some smaller data example.
