Hi Artem,

I'm getting some problem with UBIFS when the power is switched off abruptly
 during a write to flash(nandflash 2k/page). In the next boot the contents of
 the file is not found and prints the following information.

UBIFS error (pid 358): ubifs_check_node: bad magic 0xffffffff,
expected 0x6101831
UBIFS error (pid 358): ubifs_check_node: bad node at LEB 27:251264
UBIFS error (pid 358): ubifs_read_node: expected node type 2
UBIFS error (pid 358): ubifs_check_node: bad magic 0xffffffff,

UBIFS error (pid 358): ubifs_check_node: bad node at LEB 27:251264
UBIFS error (pid 358): ubifs_read_node: expected node type 2
problem renaming the file /Settings/qpe.conf.new to /Settings/qpe.conf
UBIFS error (pid 358): ubifs_check_node: bad magic 0xffffffff,
expected 0x6101831
UBIFS error (pid 358): ubifs_check_node: bad node at LEB 27:251264
UBIFS error (pid 358): ubifs_read_node: expected node type 2

I think the qpe.conf is writting when the power is off and The problem
is reproducable.

Please could you tell me if this is a known issue.

Thanks for your help and time!

Regards,

Jerry
