Comment 7 for bug 1358871

I can confirm the bug with Ubuntu 14.04 on Linux

  * 3.13.0-35,
  * 3.14.1,
  * 3.16.2 and
  * 3.17-rc4

on two machines

  * Lenovo IdeaPad Z500 Touch with Lenvo BIOS 71CN45WW(V1.18)
  * Lenovo U410 with Phoenix BIOS 65CN90WW

with all combinations of two different enclosures

  * one with ESATA plug connected with USB 3.0 adapter
  * one with USB 3.0 plug

(both with external power supply) and

  * Western Digital WD50EFRX (5 TB)
  * Samsung HD103SI (1 TB)

on

  * USB 2.0 and
  * USB 3.0 interface

An explanation can be found here: http://askubuntu.com/questions/210879/external-usb-3-drive-not-recognized (doesn't fix the issue, though).

The bug seems to be known

  * upstream: https://lkml.org/lkml/2014/3/6/284 (claims to be fixed in 3.14-rcX, but isn't (see above))
  * Debian: https://lists.debian.org/debian-kernel/2014/03/msg00153.html (regression introduced in 3.13.5, relating to upstream)
  * Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1103234 (seems to occur starting from version 18, still occurs in 3.15.x)

This seems to be a big, widespread issue for a bunch of people ("The problem is still there in 3.14.4; I haven't seen a USB 3.0 drive work for >6 months" [https://bugs.archlinux.org/task/36296]).
