AFAIK this just means that the partition was unmounted while a block
was being written and therefore the calculated block CRC doesn't
correspond to the (partial) block contents.  This can happen if
the device was rebooted by the HW watchdog.

AFAIK when the JFFS2 garbage collects these blocks the messages
will go away.
