SOLVED It is a seagate drive which can limit the link speed itself to 1.5 Gbps by setting a jumper.
http://www.seagate.com/images/support/en/us/cuda_sata_block.gif At this speed the interface runs stable. The root cause is still uncertain but this is a workaround with no drawbacks, since the drive is documented to support nothing more than 1.5 Gbps anyway. ** Changed in: linux (Ubuntu) Status: Triaged => Invalid -- Seagate ST980813ASG on Dell Vostro 1700 HD stops https://bugs.launchpad.net/bugs/196076 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
