It' s not. I catched very big problems in the do_fast_gettimeoffset() at least. In such function the jiffies static initialization change cause problems (just fixed also in other arch).
Seems that such function cause a div_by_zero fault if run when jiffies == 0 if I understand well this:
(divl %2) == (dx:ax / %2)
Unfortunately I had not time to understand what do_fast_gettimeoffset() does, I was going to work on it now.
