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
