I'm not entirely convinced it's suspend/resume related any more, but there's still a problem. When I got your email, my system had been up for awhile (running Linus' 964fe080d94db82a3268443e9b9ece4c60246414 (approximately 2.6.32-rc5) plus drm-intel/for-linus from a couple days ago for the watermark fix)), suspended and resumed several times, and logged in and out several times. I turned off wireless and power consumption was 9.0 watts. I switched to console and killed X. Power consumption still 9.0 watts. The system was almost completely idle. I rebound i915. Power consumption dropped to 7.3 watts. I restarted X and logged back in. System froze hard (whoops). It looks like something is getting the chip stuck in a high-power state. --Andy > > -- > Jesse Barnes, Intel Open Source Technology Center >
