Title:
  Immediate I/O errors when dd-ing data to an external USB3 disk

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I discovered this bug while trying to dd a potentially corrupt Btrfs
  file system to an external hard disk (see #1415510 for details).
  Unfortunately "ubuntu-bug" refused to file this report, as I'm running
  the mainline kernel (as requested in the other bug report).

  I'm running Linux 3.19.0-031900rc6-generic (x86_64) in Ubuntu Trusty
  on an IBM Thinkpad T440. I am using an external 4TB Samsung USB3 hard
  disk drive for backup purposes.

  % cat /proc/version                     
  Linux version 3.19.0-031900rc6-generic (kernel@gomeisa) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #201501261152 SMP Mon Jan 26 16:53:27 UTC 2015

  When trying to dd the content of a logical volume into an image file
  on the external disk drive (/dev/sdc1, formatted using ext4), the
  kernel immediately begins to throw I/O Errors:

  % sudo dd bs=8k if=/dev/mapper/ubuntu--vg-container
  of=/media/lenz/e2a4dc71-4c96-4dab-982c-29918e556afd/vg-container.img

  This seems to be a regression in the mainline Kernel, as the default
  kernel (3.13.0-44-generic) performed this dd operation without issues
  - but it seems to be using a different USB driver for the disk:

  Another (probably unrelated) observation: even if the file system is
  just mounted and idle (no processes accessing it), the disk drive LED
  shows activity. "iostat 3 /dev/sdc"  reveals that something seems to
  be writing to the disk continuously:
