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 From 284c154625e991be963ae3080faefc8aa4f22d01 Mon Sep 17 00:00:00 2001 From: Francesco Allertsen Date: Tue, 21 Jun 2011 15:46:32 +0200 Subject: [PATCH] Revert "drm/i915: enable rc6 by default" This reverts commit a51f7a66fb5e4af5ec4286baef940d06594b59d2.
