Kernel 3.0 runs a lot more stable but not 100%. When unplugging the machine from the docking station without turning off the external monitor before it might still crash. But it's certainly improved. I used the kernel from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Only concern I have is that AppArmor complains about missing some compatibility patch which I haven't done any research on, yet. If you find a stock standard kernel with the patch included, let me know.
