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.
