yeah appologize for not posting any info on the machine(bit tired).
Anyways here is part of lspci(I can fpast the whole thing if need be),
and dmesg of the machine running the latest Mainline.

http://fpaste.org/aSQP/

one thing I am seeing is:


[ 96.384971] [drm:i915_get_vblank_timestamp] *ERROR* Invalid crtc 0
[ 96.408364] [drm:i915_get_vblank_timestamp] *ERROR* Invalid crtc 0
[ 96.425860] [drm:i915_get_vblank_timestamp] *ERROR* Invalid crtc 0
[ 96.443365] [drm:i915_get_vblank_timestamp] *ERROR* Invalid crtc 0
[ 96.474238] [drm:i915_get_vblank_timestamp] *ERROR* Invalid crtc 0
[ 96.491728] [drm:i915_get_vblank_timestamp] *ERROR* Invalid crtc 0
[ 96.521229] [drm:i915_get_vblank_timestamp] *ERROR* Invalid crtc 0

in of which I have not seen in the past.

as for good kernel 2.6.39-rc5 survives suspend.
