That is good news that the bug is fixed in mainline. We can perform a reverse bisect and find the commit that fixes this. We first need to narrow down which version fixes the issue. Can you test the following kernels next:
v4.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/ v4.6-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc1-wily/ ** Changed in: linux (Ubuntu) Status: Triaged => In Progress ** Changed in: linux (Ubuntu) Assignee: Canonical Kernel Team (canonical-kernel-team) => Joseph Salisbury (jsalisbury) ** Also affects: linux (Ubuntu Wily) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Yakkety) Importance: High Assignee: Joseph Salisbury (jsalisbury) Status: In Progress ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Xenial) Status: New => In Progress ** Changed in: linux (Ubuntu Wily) Status: New => In Progress ** Changed in: linux (Ubuntu Xenial) Importance: Undecided => High ** Changed in: linux (Ubuntu Wily) Importance: Undecided => High ** Changed in: linux (Ubuntu Xenial) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Changed in: linux (Ubuntu Wily) Assignee: (unassigned) => Joseph Salisbury (jsalisbury) ** Tags removed: kernel-key ** Tags added: kernel-da-key -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1573062 Title: memory_stress_ng failing for IBM Power S812LC(TN71-BP012) for 16.04 Status in linux package in Ubuntu: In Progress Status in linux source package in Wily: In Progress Status in linux source package in Xenial: In Progress Status in linux source package in Yakkety: In Progress 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.
