3.17.0 impossible to test because, for some reason, it fails to boot to
X with the nvidia proprietary driver, so it is hard to test in realistic
conditions.

In any case, I would say that the issue has been introduced in the 3.16
-> 3.17 transition.

Can this be reported upstream?

Title:
  Extremely high IOWait and processes hungs after utopic->vivid upgrade
  with Iomega Zip drive (IDE)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On Kubuntu, 64 bit AMD Phenom2 machine with 4 cores, and old (Geoforge 7025) Nvidia graphics.
  Using LVM. Machine also has a 2 disk software raid (mirroring).

  The machine was working fine before the upgrade, now it is almost
  impossible to use it... I see Wait in Top always above 60%; in dmesg
  after a few minutes that the machine is up even if the machine does
  nothing. I see hung processes (typically vgs, but occasionally also
  others).  LVM related commands (e.g. lvdisplay) almost always hung at
  the terminal. I also see in ps some kernel workers almost constantly
  stuck in D state. Also, the machine takes ages to shutdown.

  Issue remains there also if I disable X (switch off the X login
  manager, sddm) and check at the console.

  Sorry I cannot provide details with apport, but the machine has been
  switched off and I will not be able to take it up again before a few
  days from now.

  The symptom I am observing may also be a sign of failing hardware, so
  please leave the bug as unconfirmed until I make some more tests or
  someone provide details on similar issues. In the meantime I would
  like to see if others are experiencing a similar serious issue. Is
  there anything specific that has changed between utopic and vivid, I
  should look into?
