Thanks for testing. We need to test some earlier kernels to identify when this bug was introduced. Once we know the last good kernel version and first bad kernel version, we can start a bisect.
Can you test the following kernel: https://launchpad.net/ubuntu/+source/linux/3.11.0-1.4/+build/4862817 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234818 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.
