It's recently fixed in mesa master commit 2d6206140a, "winsys/svga: Fix incorrect type usage in IOCTL v2", with a request to backport to mesa stable, but I'm not sure whether anyone's still maintaining the 10.1 branch. Due to the severity of the symptoms it would be greatly appreciated if this fix could be incorporated in the libgl1-mesa-dri-lts-trusty package as soon as possible.
