It seems to happen on any kernel newer than 3.13, least in my case.
Can you bisect which change between 3.13 and 3.14 caused the instability for you?
I've only downloaded kernel images as .deb files from http://kernel.ubuntu.com/~kernel-ppa/mainline/ How would I go about bisecting which change caused the instability?
