** Description changed: We're seeing a very reproducible regression in the bionic kernel triggered by the stress-ng chdir test performed by the Ubuntu - certification suite. Platform is a HiSilicon D05 arm64 server, but we - don't have reason to believe it is platform specific at this time. + certification suite. We see this on both the HiSilicon D05 arm64 server + and the HiSilicon D06 arm64 server. We have been unable to reproduce on + other servers so far. [Test Case] $ sudo apt-add-repository -y ppa:hardware-certification/public $ sudo apt install -y canonical-certification-server $ sudo mkfs.ext4 /dev/sda1 (Obviously, this should not be your root disk!!) $ sudo /usr/lib/plainbox-provider-checkbox/bin/disk_stress_ng sda --base-time 240 --really-run This test runs a series of stress-ng tests against /dev/sda, and fails on the "chdir" test. To speed up reproduction, reduce the test list to just "chdir" in the disk_stress_ng script. Attempts to reproduce this directly with stress-ng have failed - presumably because of other environment setup that this script performs (e.g. setting aio-max-nr to 524288). Our reproduction test is to use a non-root disk because it can lead to corruption, and mkfs.ext4'ing the partition just before running the test, to get to a pristine fs state. I bisected this down to the following commit: commit 555bc9b1421f10d94a1192c7eea4a59faca3e711 Author: Theodore Ts'o <[email protected]> Date: Mon Feb 19 14:16:47 2018 -0500 - ext4: don't update checksum of new initialized bitmaps - - BugLink: http://bugs.launchpad.net/bugs/1773233 - - commit 044e6e3d74a3d7103a0c8a9305dfd94d64000660 upstream. + ext4: don't update checksum of new initialized bitmaps + + BugLink: http://bugs.launchpad.net/bugs/1773233 + + commit 044e6e3d74a3d7103a0c8a9305dfd94d64000660 upstream.
