Causing ata1.00 hard resetting link Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1418 Lines: 42 Hi, I just got an external e-SATA hard disk, and I'm testing for backup. When I tried to "tar" 90GB to it, it caused a HSM violation, and since this is the root file system, system is brain-dead. "Bus error" for every command issued!
