I started a "Reverse" kernel bisect between v4.5 final and v4.6-rc1. The
kernel bisect will require testing of about 10-12 test kernels.

I built the first test kernel, up to the following commit:


The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1573062

Can you test that kernel and report back if it has the bug or not?  I
will build the next test kernel based on your test results.

In parallel to the bisect, I'll review the git logs to see if the fix
sticks out.  There are 166 powerpc commits between these two versions,
so a bisect may be the only way to identify the exact commit.

Thanks in advance

Bug description:
  memory_stress_ng, as part of server certification is failing for IBM
  Power S812LC(TN71-BP012) in bare metal mode. Failing in this case is
  defined by the test locking up the server in an unrecoverable state
  which only a reboot will fix.

  I will be attaching screen and kern logs for the failures and a
  successful run on 14.04 on the same server.
