Comment 72 for bug 1590590

Affects E5570 as well. I'm running a fully updated 14.04 machine (kernel 3.19.0-30-generic) and will try to make do with the nice workaround from bagl032 (comment #30), but would very much appreciate a proper patch of the LTS kernel because 1) the workaround doesn't work perfectly and 2) I'd hate to have to upgrade the entire (LTS release) OS to get a driver bugfix.
