to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.16 kernel[0].

tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".
Thanks in advance.

The Lenovo Yoga 2 13" models report as "Lenovo Yoga 2" or "Lenovo Yogo
2 Pro" without the size identifier. Fedora has incorporated their
version of the patch here:
https://bugzilla.redhat.com/show_bug.cgi?id=1021036
This also affects issue where the same information is shown:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1324095
The above needs to be adjusted to include the line:
DMI_MATCH(DMI_PRODUCT_VERSION, "Lenovo Yoga 2"),
DMI_MATCH(DMI_PRODUCT_VERSION, "Lenovo Yogo 2 Pro"),
