I have a RAID1 (mdadm) with two SSD Samsung 850 EVO and these days i was
affected by the same problem with linux-image-4.3.0-1-686-pae (4.3.3-2).
During these errors the system is somehow not responsive for about 30-60
seconds but at the end the operation completes and all keep working
without error or data loss. Mdadm doesn't notice nothing about these
errors: the RAID doesn't get degraded.
But it's quite annoying because happens frequently: about one time every
few minutes.
An excerpt of my errors:

---------------------------------
Like you i have an 686-pae 32 bit kernel. Have you got an SSD disk or a
rotational disk?
This morning i've tried linux-image-4.4.0-rc5-686 (4.4~rc5-1~exp1) from
experimental and everything works fine without errors. Tomorrow i'll try
the pae version from experimental to see if it works too.
Cesare.
