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. :/ On Thu, Aug 18, 2016 at 7:46 PM, Balbir Singh <bsinghar...@gmail.com> wrote: > Do we know what change fixed the issue? commit id? > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1610320 > > Title: > stress-ng memory testing causes Arm64 system to hang > > Status in linux package in Ubuntu: > Confirmed > > 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.
