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.
