There was no file in lost+found. The ls command produced the following output: [root@base-6000-67 cflashsystem]# ls lost+found =09 ???????????????????????????????????????????????????????????????????????? ???????? =09 ???????????????????????????????????????????????????????????????????????? ???????? =09 ???????????????????????????????????????????????????????????????????????? ???????? ??????????????? I didn't try du and df last week, but I'm now going to try and do it again... So, I tried again today to write the partition with 2.6.16 and read it with 2.6.25.7 and I got the following result (copy/paste of the display of the console, for ls, du and df): [root@base-6000-75 cflashsystem]# ls bert export lost+found [root@base-6000-75 cflashsystem]# du du: cannot access `./export/stream_3.SVlanId" name=3D"SVLAN ID" />\n \n \n = Why do you think this is a wide tnode issue? > >The tnodes are only relevant to the ram structures.

Ok, I didn't know about the tnodes, it was just a new option that appeared with the new menuconfig and I tried it just to see if it was helping with backward compatibility... I returned to the standard options for the menuconfig. Thank you very much for your help and advices, Best Regards, Jean-Loup
