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

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) On Fri, Aug 12, 2016 at 10:59 AM, Michael Reed wrote: > I just ran this on 4.4.0-34-generic from

I just ran this on 4.4.0-34-generic from the dev ppa on an arm64 system and it passed. I am re-running this now to see if it reliably passes. ubuntu@ubuntu:~$ sudo apt-cache policy canonical-certification-server canonical-certification-server: Installed: 0.28+201607151353~ubuntu16.04.1

I built a v4.4.16 kernel, which can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1610320/v4.4.16/ Can you give that kernel a try? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.

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,

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. ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in

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. -- You received this bug notification because you are a member of Kernel Packages, which

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
