<pre>Hi,
so with drm-tip as of the most-recent commit
commit fe5bde58dca53de7b615789c69ed83c6420d2d1a (HEAD -> drm-tip,
origin/drm-tip, origin/HEAD)
Author: Maarten Lankhorst <<a href="mailto:maarten.lankhorst@linux.intel.com">maarten.lankhorst@linux.intel.com</a>>

anymore. Unfortunately, the laptop was just running, I haven't been using it
during that time, but maybe it is really fixed in drm-tip!
I will add some dmesg dumps from the fe5bde58dca53de7b615789c69ed83c6420d2d1a
kernel. I wonder why is the kernel logging so dense if both the internal LCD
and external LCD via HDMI are turned off.</pre>
