Public bug reported:

Silicon Image 3114 and 3124 seem to have data corruption at writing data 
(particularly with big files or when the writing concern lot of files).
I used a PCI card with the Sil 3114 chip; when copying files and directories 
from a HDD to an other, data corruption appears and seems to be random in files.
But every checks about the computer (RAM, HDD ...) have gone right.
Don't know what happening really, but I supposed that the module which control 
the Sil 3114 (and so the Sil 3124, cause this module was written from the 
3114's module) contain a bug.
I've tried to enable the Sil 3114 module's option called "slow_down" which 
should solve some "problems", no difference with and without this option 
activated. The Sil 3124 module's doesn't have this option. 

I have already posted a question :
https://unix.stackexchange.com/questions/564067/file-corruption-
between-2-hdd with more precisions about what have done until now.

Now i use a PCI card based on the Sil 3124 controller, seems to have the
same data corruption issue as the Sil 3114, but less pronounced (less
often).

Running Ubuntu 16.04 server i386 with Linux Kernel 4.4.211.
