I'm personally not an xfs expert, but let me leave those two comments:
- The test was unfortunately done on an old and outdated kernel from 16.04.1:
4.4.0-36
which got already replaced by several newer kernels
Today we are already on level: 4.4.0.127.133
(and an even newer one is in the 'pipe' - in proposed: 4.4.0.128.134)
$ rmadison --arch=ppc64el linux-generic | grep xenial
linux-generic | 4.4.0.21.22 | xenial | ppc64el
linux-generic | 4.4.0.127.133 | xenial-security | ppc64el
linux-generic | 4.4.0.127.133 | xenial-updates | ppc64el
linux-generic | 4.4.0.128.134 | xenial-proposed | ppc64el
So please always update the kernel to the latest version from
<ubuntu-release>-updates
(or even proposed) before running such kinds of tests.
Just make sure you have access to the updates (Ubuntu archive mirror) and do
(something like):
sudo apt update && sudo apt full-upgrade && sudo apt autoremove
(and in case a kernel update was installed, reboot to activate it)
So please re-run this test on the latest 4.4.0 version (today either
4.4.0.127.133
or even 4.4.0.128.134 from proposed.)
- Does this problem also happen with the (latest) upstream 4.4 kernel?
Knowing this would help to narrow down the issue.
