JFFS2 problem when data cache enabled

[S. Hebbar]

Hello,

I am experiencing JFFS2 FS problem when I enable data cache on 8260 based
custom board.  (266/166/66 MHz).

While the node is booting up, I get the following error on the console.
I am using linuxppc-2.4.20-denx. with latest patches for JFFS2 and MTD.

The board has 8MB of AMD AM29LV641 chipset.

When I disable the datachache on linux kernel, everything works fine.

Any help on debugging this problem is very much appreciated.

Thanks,
Hebbar.
