I managed to boot a debug kernel when /mnt/userdata was showing jffs2
errors. "ls /mnt/userdata" returns IO error.

aseries# ls /mnt/userdata
JFFS2 warning: (1783) jffs2_get_inode_nodes: Eep. No valid nodes for
ino #2.

Yes it is.

aseries# ls /mnt

The /mnt/userdata partition is the one where files have XATTRs.

Are others using XATTR with jffs2?
