Please compile with CONFIG_JFFS2_FS_DEBUG=2 and log all the messages 
during the mount. There'll be lots -- use a serial console and log them 
directly to a file. They'll be at KERN_DEBUG loglevel too, so if it's your 
root file system then edit kernel/printk.c to make sure they actually get 
printed (change DEFAULT_CONSOLE_LOGLEVEL to 9).

Then compress them and send them to me directly.
