Re: Linux 2.6.29-rc1

During booting system stops on this message:
http://unixy.pl/maciek/download/kernel/2.6.29-rc1/laptop/img_0001.jpg

Probably I have two separate problems: warning (fragment is visible on
top) and freeze of system. I try bisect, but I have problem:

root@gumis:/usr/src/git/linux-2.6# git bisect start
root@gumis:/usr/src/git/linux-2.6# git bisect bad

I have only "fs" and ".git" directory after last "git bisect good".
How to avoid this problem?

During bisect, when I can boot i saw full warning from top of the picture:
