The 3.11.1-0xx are upstream kernels and not Ubuntu kernels. The Ubuntu kernel starts off as an upstream kernel, v3.11.3 in the case of 3.11.0-11.17, then Ubuntu specific patches are applied on top. It appears this bug was introduced by one of the Ubuntu specific patches, since you don't see the bug in any of the upstream kernels.

Can you test the previous, Ubuntu kernel, which is 3.11.0-10.16? It can be downloaded from:
https://launchpad.net/ubuntu/+source/linux/3.11.0-9.16/+build/5055306

You would need to download and install both the linux-image and linux-image-extra .deb packages.

It might also be worthwhile to test the latest Saucy kernel in the -proposed repository. It can be downloaded from:
https://launchpad.net/ubuntu/+source/linux/3.11.0-12.19/+build/5088396
