Comment 21 for bug 1729337

Ok this is very weird, it worked fine after the first reboot, but then I booted once again with 3.13.0-135-generic #184-Ubuntu just to confirm that the same mount options where failing (which they did). Then I rebooted again to 3.13.0-134-generic #183~lp1729337Commit5165d87e224 and the mount it's failing just like with 3.13.0-135-generic #184-Ubuntu

$ sudo mount -o remount -a
mount error(22): Invalid argument
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Not sure what to think of this now
