hi, list

I have merged mtd-snapshot-20040919 with jffs2 into my kernel-2.4.20. I use jffs2 as root filesystem, mounted read-write. But when I create and remove some files(dirs), and then reboot, jffs2 complains something like the following:
jffs2_get_inode_nodes(): Data CRC failed on node at 0x01aa0b3c: Read 0x14932849,
calculated 0xae8acdd4

jffs2_get_inode_nodes(): Data CRC failed on node at 0x004c2ac8: Read 0x1c81ddb0,
calculated 0x33f397d4

jffs2_get_inode_nodes(): Data CRC failed on node at 0x004c1f60: Read 0x1c81ddb0,
calculated 0xcc623008

It seems that more files created and removed, more messages like that come out.

Is that minor? Or something is going wrong? Any comments please?

Hi.
I think a quick search will give you the answer you need. (Basically, don't worry about it.) I also get these all the time.

I think it's more connected to when you power off your machine.
