各位工程师，你们好，
我在调试omapl138时运行了ubi文件系统，文件系统烧写在Nandflash中。设备在启动时会出现以下错误提示。
UBIFS error (pid 1): read_block: bad data node (block 22, inode 78)
UBIFS error (pid 1): do_readpage: cannot read page 22 of inode 78, error -22
UBIFS error (pid 1): ubifs_decompress: cannot decompress 3099 bytes, compressor lzo, error -22
UBIFS error (pid 1): read_block: bad data node (block 7, inode 78)
UBIFS error (pid 1): do_readpage: cannot read page 7 of inode 78, error -22
UBIFS error (pid 1): ubifs_decompress: cannot decompress 3099 bytes, compressor lzo, error -22
UBIFS error (pid 1): read_block: bad data node (block 7, inode 78)
UBIFS error (pid 1): do_readpage: cannot read page 7 of inode 78, error -22
Kernel panic - not syncing: Attempted to kill init!
请问出现这种错误大概会是什么原因，另外是否可以解释一下错误码“-22”代表什么意思，谢谢。
