INT3406 ACPI device object resembles an ACPI video output device, but its
_BCM is said to be deprecated and should not be used. So we will make
use of the raw interface to do the actual cooling. Due to this, the
backlight core has some modifications. Also, to re-use some of the ACPI
video module's code, one function has been exported.

Did this patch show up in -next for the first time last night, or did
some other change break this?

It causes a panic in i915 when booting Minnowboard Max for me.

Sorry for the trouble, I'm looking at this now.
Is there anything special about the Minnowboard Max? I'll try to
reproduce the issue here locally with a typical Intel desktop.

Another good question is why the code showed up in -next today. Code
going in for 3.19 is supposed to have been baking there already, and
it's too early to stage anything for 3.20.

Zhang?

well, my Linux machine happened to be broken when I was in travel in Oct
and Nov, so that I got the 3.19 material prepared a little late.
Thus I just took some fixes and driver specific patches and plan to push
my pull request next week.
For this one, it had been pushed to linux-next for 3.18, but was dropped
because of some Kconfig problem. So I thought it was safe to include
this one for 3.19.
sorry for bring the trouble here.

Now my intention is to see if we can have this problem fixed by this
Fri. If not, I will drop it for 3.19. is it okay for you?

thanks,
rui

Is it the next/master branch?
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

Yes. But I've confirmed that it happens with Zhang's next branch too
without the rest of linux-next.
