Public bug reported:
Yesterday an hour before shutdown my /home became read-only, with the
below error appearing in dmesg. Upon boot today, I encountered emergency
mode, and the superblock checksum was corrupt, needing debugfs repair,
as I disabled backup superblocks. Specifically-enabled superblock
features are also listed. Please prevent this cause of filesystem
corruption next time.
