The Linux Kernel 2.6.32 is reaching its end of life [1] after over 5 years. Instead it is recommended to use at least kernel 3.2 which is also already over 3 years old. All older kernels (v2.6.32 - v3.1) should therefore be dropped to reduce the test time. The amount of tested kernels jumps down from 33 kernels to 20.
