--- Comment #8 from Jan Kara <jack@...e.cz> ---
Ah, OK. I've checked the code again and now I see the problem. The message is
about jqfmt being specified but no quota file name. But there's no way to zero
out jqfmt on remount. So the only way to get rid of quota options is to unmount
the filesystem (= reboot for you since this is your root filesystem).

Attached patch should fix your problem.
