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.

I've done the following tests that seems to prove that the bug is with
the PAE kernel, also the last 4.4.0-rc5:
* Boot with linux-image-4.4.0-rc5-686 (4.4~rc5-1~exp1): OK.
* Boot with linux-image-4.4.0-rc5-686-pae (4.4~rc5-1~exp1): ata errors.
* Boot with linux-image-4.3.0-1-686 (4.3.3-2): OK.
* Boot with linux-image-4.3.0-1-686-pae (4.3.3-2): ata errors.

Also, today i had error both on ata1.00 and ata3.00, while yesterday
were only on ata1.00.

I've fscked 2 filesystem out of 3 and are ok. In my case looks like
that those read/write instructions that timeouts, at the end succeed.

Until now with a PAE kernel i can usually trigger the errors with a
simple "apt update" and the system is almost unusable with those
kernels: too many timeouts.
In the meantime i'm now running with non-pae 686 kernel.

Cesare.
