UBIFS error CRC calculation on avr32 CPU

[Eirik Aanonsen]

Hi

I get this problem running my ubi/ubifs on a partition in my system.
The error occurs when I try to move one file to a new location and there
seems to be something wrong with the file. The file contains binary data
and is 9.3MB large. Can anyone help me locate this error or point me in
the right direction?

My system is a ap7002(arch == avr32) with 32MByte SRAM, 8MByte NOR flash
and 2GByte NAND flash(ubi).

Cmd:
----
/mnt/slave # mv wpr_004.wfp ../master/data/

UBIFS error (pid 471): ubifs_check_node: bad CRC: calculated 0x582d0a64,
read 0x4932021b
UBIFS error (pid 471): ubifs_check_node: bad node at LEB 159:302512
UBIFS error (pid 471): ubifs_read_node: expected node type 1
UBIFS error (pid 471): do_readpage: cannot read page 24 of inode 34213,
error -117
mv: read error: Input/output error


The file causing the problem:
-----------------------------
-rwxr-xr-x    1 root     root      9717632 Nov 28  2008 wpr_004.wfp
