Empty flash at ... / check_node_data: wrong data CRC

[Arno Steffen]

I do have a system which is not used with a controlled shutdown, but
with a cold heartless poweroff only.

I am using a jffs2 filesystem as it should be journalling and robust
agains power loss.

But while boot I get  messages like:

Empty flash at 0x00963864 ends at 0x00964000

And after finishing boot:

[root at EEE ]# JFFS2 notice: (181) check_node_data: wrong data CRC in
data node at 0x01f8b55c: read 0xa7496669, calculated 0x5aea21d5.
JFFS2 notice: (181) check_node_data: wrong data CRC in data node at
0x01f88d3c: read 0xc5d341c, calculated 0x3f0d9534.

This sound seroius to me. How to prevent this if I can't use "halt" or
other controlled shutdown?
