jffs2 file corruption

Trying to (still) update from 2.4.20 to 2.4.27 on an x86 embedded unit.
Made the kernel with CVS from 20040826 ( and added in the __ffs macro from
the previous thread ).
Running on a 486 with 16mb Intel flash, 128k size erase sectors. To create
the file system I run :
mkfs.jffs2 -o romfs.img -U -n -p -e0x2000 -d romfs/
Bootup seems fine, but I get a lot of file anomalies. I have a 24MB RAMFS on
/mnt/ramfs and then a sym link /mnt/ramfs -> /tmp . After bootup I get
wierd errors like :
[root at JBMgateway-60b /]# ls -al

Modifying a simple test file seems fine, but then when rebootnig, here come
the CRC errors, and then the file system is unreadable.
