I've had no luck getting any response from the linux-mtd mailing list regarding the issue reported below. I think it is a very serious issue since it can easily render an embedded system unusable.

We recently encountered a strange issue where UBIFS recovery is suddenly taking a lot longer than usual (v3.7-based kernel). In our case, recovery took about 30 seconds. This caused a serious problem because our watchdog timer was set to 15 seconds, effectively rendering the devices unbootable.
Does anybody know what triggers this slow recovery mode? Also, how can we calculate a worst-case recovery time for a given flash chip-size.
Thanks,
