Pretty good actually.

That looks like transmission failure and to me it doesn't seem to be a
driver problem and please don't add your drive to sata_sil blacklist.
The blacklist is for very specific cases and won't fix your problem
other than sometimes hiding the real problem by slowing things down a lot.

When does such error occur? Is it reproducible? How often does it occur?

Can you give a shot at 2.6.18? It contains improved EH which should be
able to recover from the condition you described.
