Title:
  stress-ng memory testing causes Arm64 system to hang

Status in linux package in Ubuntu:
  Invalid

Bug description:
  Running the certification memory test using stress-ng on an ARM64
  system with 64GB roughly of RAM (MAAS shows 63GB).

  The test runs several stress-ng memory related tests.  It appears that
  the system locks up when the bigheap test runs, every time so far (two
  of two runs have failed).

  I'm doing a third now to confirm that bigheap is where the lockup
  occurs.

  I've also run this exact same test on similar and smaller memory
  amounts on s390x and amd64 without problem.

  This is also being done to provide data for a similar bug discovered
  on Power (ppc64le).

  To test this on an arm64 system:

  Install Xenial
  $ add-apt-repository ppa:hardware-certification/public
  $ apt update
  $ apt install canonical-certification-server
  $ /usr/lib/plainbox-provider-checkbox/bin/memory_stress_ng

  the memory_stress_ng script is a wrapper for stress_ng that only calls
  certain memory tests.  See script for an idea of how it's executing
  the tests.

  This could be the same issue that we're seeing on power, or it could
  be a different issue for ARM that looks similar.  Here's the original
  Power bug:

Re: [Kernel-packages] [Bug 1610320] Re: stress-ng memory testing causes Arm64 system to hang

2016-08-23 Thread Jeff Lane 
Not yet... I've tried 4.7.0-040700 on a 64GB arm64 system with no
failures.  I've also tried 4.4.0-33.52 on a 32GB ARM64 system with no
failures.

Currently trying 4.4.0-21.37 on the 32GB system and 4.4.0-34.53 on the
64GB system.  I initially saw this on  4.4.0-31.50 on both systems, so
I had expected 21.37 to fail immediately, but it's survived two passes
so far. :/

Any chance you can back to -31 (16.04.1 stock) and see if it fails
there?  That's where I was failing on my systems, I'll see if I can
grab -34 and give that a try too)

Bug description:
  Running the certification memory test using stress-ng on an ARM64
  system with 64GB roughly of RAM (MAAS shows 63GB).

  The test runs several stress-ng memory related tests.  It appears that
  the system locks up when the bigheap test runs, every time so far (two
  of two runs have failed).

  I'm doing a third now to confirm that bigheap is where the lockup
  occurs.

  I've also run this exact same test on similar and smaller memory
  amounts on s390x and amd64 without problem.

  This is also being done to provide data for a similar bug discovered
  on Power (ppc64le).

  To test this on an arm64 system:

  Install Xenial
  $ add-apt-repository ppa:hardware-certification/public
  $ apt update
  $ apt install canonical-certification-server
  $ /usr/lib/plainbox-provider-checkbox/bin/memory_stress_ng

  the memory_stress_ng script is a wrapper for stress_ng that only calls
  certain memory tests.  See script for an idea of how it's executing
  the tests.

  This could be the same issue that we're seeing on power, or it could
  be a different issue for ARM that looks similar.  Here's the original
  Power bug:

[Kernel-packages] [Bug 1610320] Re: stress-ng memory testing causes Arm64 system to hang

2016-08-09 Thread Joseph Salisbury 
That is good news the 4.7 kernel does not exhibit the bug.  We should be
able to perform a "Reverse" bisect to identify the commit that fixes the
bug.

We should next test the latest 4.4.16 upstream stable kernel to see if
the fix was already sent to upstream stable?

If 4.4.16 still has the bug, we should then see if upstream 4.6 has the
bug.

However, the arm64 kernels were just recently added to the automatic
build process in 4.7, so I'll manually build you those kernels.

So running the upstream 4.7.0 kernel and had 0 failures out of 31 runs
so it's pretty safe to assume that this isn't an affect upstream.

[Kernel-packages] [Bug 1610320] Re: stress-ng memory testing causes Arm64 system to hang

2016-08-05 Thread Jeff Lane 
This appears to reliably happen with the bigheap test on ARM64.  I've
tried two systems and both lock up shortly after the bigheap test
begins.

This may need some input from @cking as stress-ng is his test.

[Kernel-packages] [Bug 1610320] Re: stress-ng memory testing causes Arm64 system to hang

2016-08-05 Thread Joseph Salisbury 
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.
