ubifs_decompress: cannot decompress ...

[Matthew L. Creech]

Hi,

We encountered a device which has the following error:

UBIFS error (pid 428): ubifs_decompress: cannot decompress 1010 bytes,
compressor lzo, error -22
UBIFS error (pid 428): read_block: bad data node (block 388, inode 556196)
UBIFS error (pid 428): do_readpage: cannot read page 388 of inode
556196, error -22
UBIFS error (pid 428): ubifs_decompress: cannot decompress 1010 bytes,
compressor lzo, error -22
UBIFS error (pid 428): read_block: bad data node (block 388, inode 556196)
UBIFS error (pid 428): do_readpage: cannot read page 388 of inode
556196, error -22

The device is still bootable (though not functional), so I can get
more debug info if needed.  Any ideas on what could cause this?

- MPC8313 (using fsl_elbc_nand driver)
- 1GB NAND flash (partitioned into 5MB for U-Boot, remainder for UBI/UBIFS)
- 2.6.39 kernel

Thanks!
