Yes, you _HAVE_ _ABSOLUTELY_ to use it !  
IF not, no buffering and OOB check, no bad block management ..--> no
JFFS2 on NAND.

I meant, could you get full logs with CONFIG_JFFS2_FS_DEBUG=1 from

serial console so you catch _ALL_ the messages, and remember they're at
level KERN_DEBUG so echo 9 > /proc/sys/kernel/printk before mount.
