It's the Data CRC which is failing, so the node header should be fine,
and should happily identify the inode to which it belongs. At 0x2aedb74
on the flash, you'll find a struct jffs2_raw_inode (see
include/linux/jffs2.h for its definition).

It's almost certainly harmless though -- just a poweroff which happened
while the node was being written and before it was even *expected* to
have hit the medium.
