What is the output of blkid? I recall reading a similar problem on the
forum (https://bbs.archlinux.org/viewtopic.php?id=137255) where the problem
was caused by an update to util-linux which had changed the uuid of the
root partition so that the root could not be correctly remounted rw.

Hope that helps.
