I built the next test kernel, up to the following commit: 16b9057804c02e2d351e9c8f606e909b43cbd9e7
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1398597 Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

On boot the mouse pointer is not visible. If I open terminal and do "rmmod psmouse; modprobe psmouse" the pointer magically appears on first touch. Please help me as to how I can bisect / track down what the issue here is. Sometime in the past it was working reliably.
