This commit makes suspend to ram unreliable for me:

drm/i915: implement BSD ring buffer V2 The BSD (bit stream decoder) ring is used for accessing the BSD engine which decodes video bitstream for H.264 and VC1 on G45+. It is asynchronous with the render ring and has access to separate parts of the GPU from it, though the render cache is coherent between the two.

#define HAS_BSD(dev) (0)
with this change applied suspend to ram is back to the reliability of 2.6.34.y
with kind regards thomas
Added CCs.
Thomas, on what hardware did you observe the regression?
Is a Intel mobile express gm45 chipset.
Is it suspend or resume that is unreliable?
suspend never finishes/hangs.
What are the particular symptoms --- does not suspend, crashes during suspend, crashes during resume...?
Does not suspend, backlight is on.
Could you help report a bug for this issue by following http://intellinuxgraphics.org/how_to_report_bug.html
Thanks --Shuang
