Running with a 3.19.0-8-generic kernel I see:

- The Upstart test_job_process test fail within a few seconds when run in a loop looking for the errror.
- My test program in #13 also finds the bug within ~30 seconds on my test system.

Using the kernel in #11, I have run both tests simultaneously for ~1
hour with no errors observed.

** Changed in: upstart (Ubuntu Vivid)
       Status: New => Invalid

** Summary changed:

- FTBFS: upstart test_job_process fails in majority of cases / Kernel returning unexpected EIO at near of file
+ FTBFS: upstart test_job_process fails in majority of cases / Kernel returning unexpected EIO at end of file

Bug description:
  As you see in the history in https://jenkins.qa.ubuntu.com/job/vivid-
  adt-upstart/?, upstart's test fail almost all the time, on

  ok 53 - with single line command writing fast and exiting
  not ok 54 - with single line command writing lots of data fast and exiting
   wrong value for bytes, expected 3145728 got 3018027

  FAIL: test_job_process

  Sometimes they succeed on one architecture, and with lots of luck on
  both, but this is way too flaky to be an useful test. This keeps
  blocking the propagation of other packages from -proposed.

  This was most likely triggered by the kernel update from 3.18 to 3.19.
