(snip, it goes like that on)

I've built just before source from git pull and it worked without such 
bug. Will it be fixed at last? I've reported it on linux-next group 
without response and here - without solution. It annoys me because I 
dont know what I am typing when I build nvidia graphics driver straight 
after boot. I attach relevant files.


Cheers,

Piotr Hosowicz
