Hi, first of all, I use 10 on my X220 since end of May. I do not use currently suspend and resume on my X220. I use a script for the brightness which makes it easy to handle for me. There was (is) a problem with iwn I did not find the time to investigate with a new kernel until today. We use the X220 for serious work presenting our product/company to clients. As crashes would not shed a good light on us, a reliable machine is the minimum we have to have. In all this we experienced only one problem once in a while. The machine crashes the moment X starts. As this only happens when the machine is freshly started, we start X long before we start the presentation. There is a fundamental problem with powerd which stops a notebook to get better battery life time. powerd does not include the display brightness and it does not inlcude user activities in its process to regulate the CPU speed. In addition, the algorithm to find the best CPU speed gets easily irritated with short bursts of peak performance requirements.
