 Thanks. That was execly what I expect to hear. (: The driver which causes
 npx dne was ported by me and I tend to change all maths to fixed point
 arithmetics in near future. The patch I've send was a quick hack to see if
 driver realy works. But after argue with my coleeg (who think that FP is
 normal in kernel mode and patch realy fix some problem) we decide to submit
 it and see who was right.
