Ran the reproducer on both a HiSilicon D05 and D06 and it now passes. ** Tags removed: verification-needed-bionic ** Tags added: verification-done-bionic

[Test Case] We use the Canonical certification test suite, which wraps various stress-ng tests, to reproduce this: $ 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 [Fix] We applied a partial fix for a regression in LP: #1780137 - that applied to inode bitmaps. We also need a fix for block bitmaps. https://marc.info/?l=linux-ext4&m=153143692320723&w=2 [Regression Risk] With the proposed fix, the above test case passes reliably. I'm not an expert in the code though, so I don't have a good feel for the risks to it.
