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

Status in “linux-meta” package in Ubuntu:
  New

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.
