Same here. Even if a background fsck is being run, the file
system still kept some corruptions and would not be marked
clean, so the same thing repeated at next boot. A forced full
foreground fsck (!) would sometimes fix it, sometimes two (!)
runs were needed. By switching off J things went back to
normal again.
