I'm attempting the same and run into a symbol resolution problem in lib/ext3.o whether I use mkinitrd with 'defaults,data=journal' as my fstab ext3 options or I manually tag '-o data=journal' to the / mount command in linuxrc on the initrd image. Is the Redhat 7.2 stock kernel capable of running in data=journal mode? Would there be additional module dependencies in that mode or do I just have something else wrong? (The filesystem is running ext3 with the defaults just fine). If someone has a recipe that'd be great.
