[Regression] EXT4-fs error (device sda1):
ext4_validate_inode_bitmap:99: comm stress-ng: Corrupt inode bitmap
Status in linux package in Ubuntu:
Status in linux source package in Bionic:
We're seeing a very reproducible regression in the bionic kernel triggered by
the stress-ng chdir test performed by the Ubuntu 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.
$ 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
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
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:

ext4: don't update checksum of new initialized bitmaps
commit 044e6e3d74a3d7103a0c8a9305dfd94d64000660 upstream.
Reverting that fixes the problem. Meanwhile, a proposed fix has been posted
