How do the entries in /proc/self/mountinfo look like? Do they have the same mount options there? Note that data=ordered is the default anyway, so the two option strings are effectively identical. My guess is that the string is not passed in from userspace but added by the kernel, and the kernel is broked and sometimes omits adding this, and sometimes doesn't.
