I can't reproduce this on 2.4.18 with the mtdram device, with either the 
2.4-branch code or the trunk. Can you reproduce it on mtdram or only on 
your flash? I'd have expected the name_crc to catch any flash errors, 
unless we've done something completely stupid like not including the 
final byte of the name in the crc. Can you set CONFIG_JFFS2_FS_DEBUG=1, 
mount an empty flash or mtdram device and create only one such file, then 
unmount and remount it and send me the logs?
