Thanks for testing the upstream kernel. Since the bug is fixed in 4.13-rc4, we should be able to perform a "Reverse" bisect to identify the commit that fixes the bug.
We first need to identify the last kernel version that had the bug and the first kernel version that did knot. Can you test the following kernel: 4.13-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13-rc1 ** Changed in: linux (Ubuntu) Status: Incomplete => In Progress ** Changed in: ubuntu-power-systems Status: Incomplete => In Progress ** Changed in: linux (Ubuntu) Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) => Joseph Salisbury (jsalisbury) -- 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/1709738 Title: xfstest sanity checks 17 fails on data-hole-data inside page Status in The Ubuntu-power-systems project: In Progress Status in linux package in Ubuntu: In Progress Bug description: Problem Description ---------------------------- xfstests fails with Metadata corruption at leaf on ext4 filesystem Environment ------------------ Kernel Build: 4.12.1-041201-generic System Name : ltc-test-ci2 Model : 8247-22L Platform : PowerNV ( P8 ) Issue observed in P9 also.
