[Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>]

I started a kernel bisect between v3.15 final and v3.16-rc1. The kernel
bisect will require testing of about 7-10 test kernels.

I built the first test kernel, up to the following commit:
aaeb2554337217dfa4eac2fcc90da7be540b9a73

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.

Thanks in advance

Title:
  ideapad yoga needs psmouse reload

Status in linux package in Ubuntu:
  Triaged

Bug description:
  So, my often made fun of, lenovo ideapad yoga, since sometime in the
  14.10 development cycle needs an extra help to get the trackpad
  working.

  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.
