I tried to install 10.9 on my X201 following the guide, but I couldn't boot into the Mavericks HDD partition.
It always got stuck at "kernel[0]: flow_divert_kctl_disconnect (0): disconnecting group 1". Mine is not X201s, but X201 with i7 620m. When I boot, I used the following options "-x -v GraphicsEnabler=No".
Does anyone have experience with this error on similar model as mine? Any suggestions would be highly appreciated. Thanks!
