@Daniel: if you're referring to LP: #1315433, that's not really the same issue, as it refers to Linux 3.15 (it looks like a custom kernel), that is not in 14.04 (at least not yet), as per the bug's description:
DKMSKernelVersion: 3.15.0-rc2-eudyptula-00206-g9310072
I haven't added support for 3.15 in Utopic in any of the binary drivers yet.
