Hello.

I work on a system where we need to be as 100% uptime as possible.  The 
other day we had an issue here where one of our applications was 
crashing while a write to one of the partitions was happening.

I then turned on UBIFS debugging in u-boot and I have a bunch of info 
but I have no idea what is going on.

Here is the output after (at the u-boot) prompt I do:

ubi part nand0,1
ubifsmount boot-info

"boot-info" in one of our volumes that has boot information that we use 
in u-boot.

Here is the output I get....
Any help I can get debugging this is much appreciated.

I also have alot more output... but I've just put the tail end of it here.


Thanks so much.
