Hi, I wanted to try the new 3.0 Linux Kernel, and I got stucked for a
freeze at the start of X.

I have bisected the problem and the error was on commit a51f7a6, wich
enable rc6 by default (some time ago I have sent another bug about
that).

I have reverted the commit (the complete patch is attached) and now
everything works great.

Now, I have a Lenovo X201s, and if you need more information for
debugging purpose just let me know, otherwise just apply the patch
attached (on top of -rc4).

If you prefer I can send the patch using git-send-email.

Thanks

Bye
Francesco

This reverts commit a51f7a66fb5e4af5ec4286baef940d06594b59d2.

With rc6 enabled by default there is a freeze in the Lenovo X201s
laptop.
