Mounting issue with old rootfs and new kernel

[Jaap de Jong]

Hi

I'm hoping for some pointers.

I have this a created with openembedded classic.

It works just fine when running with an old kernel (2.6.35)

Now with the same rootfs and a newer kernel (4.9.28) it damages the old 
rootfs in such a way that it becomes unusable.

This is the error it shows:

                         [    1.523437] ubi0 error: 
ubi_read_volume_table: the layout volume was not found
                         [    1.531250] ubi0 error: ubi_attach_mtd_dev: 
failed to attach mtd3, error -22
                         [    1.539062] UBI error: cannot attach mtd3
                         [    1.546875] Kernel panic - not syncing: VFS: 
Unable to mount root fs on unknown-block(0,0)
                         [    1.546875] Rebooting in 1 seconds..RomBOOT

As far as I can see the kernel configuration seems to be ok.

Any ideas?

Thanks!

Jaap
