Bug Description

Dear all,

In order to be able to upgrade one of our servers to the latest LTS (14.04), we need that the Samsung SSD 8 series to be blacklisted from the libata for the TRIM command.
Due to the bug described here [1], not having the SSD blacklisted would lead to data corruption which we cannot afford.
The Samsung SSD was blacklisted with that commit [2].

I checked, it's not present in current Trusty kernel. Could you please backport it?

With my best regards,

As we are anticipating the issue, based on others feedback, we don't have logs.

And having logs for data corruption sounds highly difficult to obtain.

So, confirming it.
