Hi,

I was testing some code on my (Armada 370-based) ReadyNAS 102 and got
the following error while writing something on disk on *3.12-rc4* (also
happen on -rc3):

I though this was an hardware issue and replaced the disk by another
one with an already installed system (Debian armel for the former,
Debian armhf for the latter). After some minutes, the same kind of
problem occured. When asking smartctl, both disks have a PASSED
status. I rebooted on a 3.11.4 kernel and never got the issue.

Looking at commits touching other armada-370 .dts file, I do not think I
missed any specific changes so - I may be wrong - but it is possible
that what I get is also happening on other mvebu boards *which do use*
sata disks. Before trying and look where it comes from (sounds
promising) to put different subsystem maintainer in Cc:, it would be
good to know If I am the only one to get that and/or understand if it is
mvebu, sata or anything else related.

So if you have such a board with a sata disk connected, it would be nice
if you could give 3.12-rc4 a try and report what disk-related operations
produce.

If you have any other idea where it may come from, do not hesitate.

Cheers,

ps: FWIW, here is what I get at boot in the log regarding sata config:
