OK, I've taken the patch, and it's not in the latest linuxppc_2_4 tree on which I'm working (when I began working, this was 2.4.20-pre7 I think its now in -rc1).
This is what I expected :-(
Surprisingly (or not...), my /dev/nftla partition now works! I formatted it under ext2 and it survived reboots without getting corrupted.
Fine.
Now I have another problem - when I write my working kernel on the doc at sector 0, and read it back, booting it fails with a CRC error, and 'cmp' fails.
How _exactly_ do you erase + format + write your DoC? Maybe you can show a full log?
when I look at the first 16-32 bytes before/after saving/loading the image on the DOC, it seems that the corruption is only at part of the image, and that its reproducible (retrying get the same corruption).
F'up to MTD?
