I tried with 3.11.1 and that one's still good. I don't know if I can
get a kernel built but might give a try later and can't reboot the
machine at the moment anyhow.

Don't you think https://git.kernel.org/cgit/linux/kernel/git/stable
/linux-stable.git/commit/?id=cc0ffca95bf3e8cd393327c444c5bf4493deda90 is
at fault?

This is a dupe of bug #69791.

In general _please_ file new bug reports, it's much easier for us to
mark a bug as a duplicate than to untangle a maze of me-too reports that
effectively are all different bug reports.

I know that bugzilla gives you a neat list of possible dupes, but
ignoring that is usually the best option. Of course if an upstream dev
told you (on irc or so) that there's a bug report already that's
different.
