jffs2 top-boot errors

[Ganesh Ragavan]

Hello,

I am trying to boot up linux on a Macronix MX29LV128DT flash in a
powerpc architecture.  This is a top boot flash of size 16 MB in size.
 There are 255 sectors with 64KB in size and 8 sectors with 8 KB in
size.

The u-boot and kernel boots up completely, but I see lot of the
following jffs2 errors while booting and also while doing firmware
upgrades.  I verified the checksum of the jffs2 partition in u-boot
before the kernel boots and they seem to be fine.  Is there any
partition info I need to pass to jffs2 or mtd ?  Mtd seems to probe
the chip and report the values correctly.  Mtd probe values are also
below.  Linux version is 2.6.18.

It would be great if someone could suggest a fix for this.

JFFS2 Errors:

(these errors are not consistent, different kind of jffs2 errors are
got every time)
