According tests I have found that problems are while writing data, not while
reading.

Hello, Kacer.

Yeap, I did received your message and forgot to reply. :-p Anyways, 
currently there isn't any sil3112 errata applicable to your case. 
Hardware problem (cabling, power fluctation, whatever) is also a 
possibility.

The problem is that currently libata EH doesn't do whole lot of recovery 
actions. libata is likely to fail to recover device after a transitional 
transmission error. EH work is in progress and hopefully it will see the 
light of day soon.

One way to confirm that your machine is experiencing transitional 
transmission errors is to test your drive under Windows. Put drives 
under heavy IO in Windows and watch the transfer rate (Windows has 
system monitoring utility which shows disk activities as graph. I don't 
remember what it was though.) and if your machine suffers the same 
problem under Windows driver, it will show occasional drops (transfer 
rate stalls to zero for quite some seconds) when such problems occur.

Hope it helped.
