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

Title:
  Regression: DisplayLink DL-195 fails with EAGAIN after upgrade from
  3.11.0-031100  to 3.11.0-11

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  My Plugable UGA-2K-A USB 2.0 to DVI adapter (using chipset DisplayLink
  DL-195, USB ID 17e9:4302) works fine with 3.11.0-031100-generic.
  However, when upgrading to 3.11.0-11-generic, X11 fails to open the
  DRI device with

  [     8.868] (EE) open /dev/dri/card1: Resource temporarily
  unavailable

  Reverting to  3.11.0-031100-generic fixes the problem. Upgrading to
  current mainline (3.12.0-999.201310030405) also fixes the problem (but
  causes lots of kernel BUG messages).

  In both cases, the kernel correctly creates the /dev/fb1 and
  /dev/dri/card1 devices. There are no error messages in the kernel log.

  I can bisect this if someone tells me where to find the intermediate
  versions.
