Comment 300 for bug 993187

I want to mention that after following the suggestion at #274 (i915.i915_enable_rc6=0) and #280 (i915.i915_enable_fbc=0), my Dell Vostro V131 with Sandy Bridge and HD 3000 has not hard crashed (no mouse movement, no SysRq, no ssh) for about a week using kernel 3.4.1 (available at http://kernel.ubuntu.com/~kernel-ppa/mainline/) while before I used to get 2-3 crashes a day. I am not sure at this point what exactly is making a difference (it could have been an update for what I know). I promise I will try to revert the settings and pinpoint what is fixing it for me. But reporting it now to let other people know that there is hope.
