Title:
  USB mounted SATA disk disconnects

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm having a problem with a SATA disk connected to a USB adapter. The
  disk is detected and its partitions mounted  but after I use it for a
  few seconds to minutes the adapter disappears and dmesg lists errors.
  If I don't use the disk it stays healthy but running 'sudo cat
  /dev/sdb5 > /dev/null' consistently causes a failure within a minute.
  The disk works well connected to the internal slot of the same machine
  and the adapter works well with a 40GB IDE disk I have on hand.

  I looked at a similar looking bug, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1012291
  and booted a kernel from
  http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2.27-precise/
  which was reported as
