Did you do something unusual, or did something unusual happen, shortly before these started? It looks like a faulty device was being "replaced" - e.g. via mdadm --replace is that correct? How many devices in the array? RAID5 or RAID6? Was it degraded? 3.13.0 is a little bit old, the 3.13 series is up to 3.13.11 which has at least one raid5 bugfix in it - it may affect this issue, but I'm not certain. Is there a kernel upgrade available from ubuntu?
