(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.

Ok, I just now uptaded the source and built the kernel - the problem apparently disappeared. I hope that it did so permanently.

Cheers,

Piotr Hosowicz
