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.
