As far as I understand the problem of this kind of errors is for the multi
sector write case. The framework does not know what sectors fails, so the
question is: does it repeat the whole multi sector sequence or what else it
does?

The entire request should get retried.

I'm not so sure that is correct.

The Linux IDE stack will not retry the completed sectors
(those which were successfully transfered in multiple-sector blocks).

Not sure what libata does here.
