Just a quick question, is this a regression? If so, can you please
attach the output of xrandr --verbose from a noisy and a quite kernel
(otherwise just please attach it from this noisy kernel).

seems so, I don't see it on 3.3

this machine runs headless, so has no X installed right now, I'll get it in a while.

The WARN is new, the problem is old.
commit c543188afb7a83e66161c026dc6fd5eb38dc0b63
Author: Paulo Zanoni <[email protected]>

drm: add generic ioctls to get/set properties on any object
Useless for connector properties (since they already have their own
ioctls), but useful when we add properties to CRTCs, planes and other
objects.

Before that commit we had no idea that we had run out of property slots.
I think the WARN is genuine, but maybe we should just bump the count set
it to WARN_ONCE and hope the conversion to lists arrives sooner rather
than latter.

Chris is right: this is not a regression. Before that patch, no one
checked if property creation really worked. I chose not to use
WARN_ONCE because we need to increase the variable once for each time
you see the message. Assuming this message appears on your log less
than 8 times, does this patch fix your problem?

Just a little more information: you have a lot of connector properties
because for some reason the driver thinks you have TV1, TV2 and TV3.
Each TV connector has a lot of properties... With kernel 3.3 you have
only TV1 and TV2. Maybe instead of increasing the maximum property
count we should try to investigate why there's a new TV connector in
the new kernel (and maybe this is also not a bug/regression...).

I've merged a patch from Chris to detect additional sdvo TV outputs:
commit a0b1c7a5197293d6206b245b45edc3f508aadab6
Author: Chris Wilson <[email protected]>
Date: Fri Sep 30 22:56:41 2011 +0100
drm/i915/sdvo: Include YRPB as an additional TV output type
So that explains that hopefully.

I've hit the same warn on my g33 with a tv-out sdvo. Seems to be enough to
shut it up.
