Ah, I think I see the problem - looks like we can enable write
barriers accidentally during a remount,ro without checking to
see if the drive likes that idea. Ugh.
Just to be sure - when you initially mounted the filesystem (rw), did
you get a dmesg message saying "disabling write barriers" or words to
that effect?
