Cirrus Logic EDB9302 JFFS2 problem

Hi all,
I have a Cirrus Logic EDB9302 pcb running Linux version 2.4.21-rmk1-crus1.4.3, and have a problem with a flash partition I created.
I followed the instructions in the Cirrus app note and setup
the kernel mtd stuff. I've used various versions of
mkfs.jffs2, up to 1.42

    mkfs.jffs2 -r partition_dir -o output_file -e 0x20000 -p,

using a 128K erase block to match the MT28F128 chip.

I download the flash file into the pcb and write it using Reboot

lo -r -v -b 0x1000000 jffs2.out
fi cr -r -l 0x400000

creating a 4M partition.

I can mount /dev/mtdblock6 and read it ok. The files cmp ok with the originals located in /etc. One thing I notice is df indicated more usage that if should be, less then 50K worth of files in a 4M partition showing 32% used ! When I starting witting or erasing files in the partition on the following remount I get various errors and corrupt files.

jffs2_scan_inode_node(): Data CRC failed on node at 0x000abc44: Read 0x189aa386, calculated 0xefa9b9b2 jffs2_scan_inode_node(): CRC failed on node at 0x000afd54: Read 0x09afa921, calculated 0xf472bf46 jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x000afd58: 0x1044 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x000afd5c: 0x586d instead .

Am I missing something ? Anyone have this problem or is it just me :)

Thanks for any feedback,
