Run 16 in parallel on /, and another 16 simultaneously on the trouble filesystem? If you continue to get errors only on the 'trouble' filesystem, and no errors start occurring on / coincident, then it sounds pretty localized.
BTW, I may have missed this earlier, but does it happen *anywhere* on the troublesome filesystem (ie, in a newly created subdirectory)?
