[Yaffs] [Empty partition after power loss]

Hi!

Did somebody have the issue when the power is lost
during a write to an YAFFS2 partition and after
the device is started again the partition was empty?

There was many files in the partition, only one was
written during the power loss event but after the
device is started again manually and I mounted the
partition it was empty - usable but empty.

There was no errors in dmesg.

How can it happen and how can I check why does it
formats (or whatever else) the partition?

Thanks for the help!
