thinkpad L412, suspend fine but always failed and freeze on wakeup, with kernel 4.4, 4.6 and 4.7, but long term kernel 3.18.40 and 4.1.33 running fine, i use source from vanilla kernel at kernel.org, for now both of them are recommended, 3.18.40 had proven for days with multiple suspend-resume cycles, 4.8.0-rc6 is running fine with suspend-resume features
