It doesn't take much to trigger it - download a ppc64le Ubuntu cloud image, boot it in KVM and run: sudo apt-get update sudo apt-get dist-upgrade sudo reboot And it never makes it back up, dying with rather severe filesystem corruption. I've narrowed it down to: 64e1c57fa474 ("ext4: Use clean_bdev_aliases() instead of iteration") e64855c6cfaa ("fs: Add helper to clean bdev aliases under a bh and use it") ce98321bf7d2 ("fs: Remove unmap_underlying_metadata") Backing these patches out fixes the issue.
