jffs2 file corruption shows up in linux kernel but not u-boot

I am using the 2.6.33 kernel.
I am also using the latest version of u-boot.
Our devices have the jffs2 filesystem on flash - mounted at /mnt/jffs2
We write a file which is about 64k to /mnt/jffs2/lib/filename.xml
On 50 out of some 500 boards, we get the error "requestied to read an nonexistent ino #25" after I do
an "ls -al /mnt/jffs2/lib"
Subsequent mounts will mount the file system - the error message above is still printed out during mounting.
The reason I bring up u-boot is that I can halt the boot process to get to the u-boot prompt, and I can
execute the command "ls". The ls command scans the jffs2 filesystem. The u-boot jffs2 scan process shows no
errors and completes printing out the filesystem listing.
It seems that u-boot has validated the filesystem, yet when I load the linux kernel and interact with the filesystem
at the /mnt/jffs2/lib the readinode.c routine in the jffs2 subsystems finds an error.
Any advice on these results??
Thanks
Jerry
