Do these oops also happen with the Ubuntu-3.13.0-15.35 kernel?  Also, do
you happen to know if they happen with the latest mainline kernel:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc5-trusty/

The oops in the following bugs all happen at different instruction pointer, so they may or may not be related:
bug 1287444
bug 1287448
bug 1287737

And just to confirm, these oops only happen when you are using the Apple
trackpad?  If it's not connected, the oops don't happen?
