Corruption in ext4 root

[W. Michael Petullo]

I have a peculiar use case for OpenWrt: an image with an ext4 root
filesystem running on Xen as a DomU.

I often find the OpenWrt image's root filesystem corrupt after running
"poweroff" and then restarting the DomU VM. I have gone as far as to
activate CONFIG_TARGET_EXT4_JOURNAL, but this does not seem to help.

It occurred to me that I might ask to see if anyone had any suggestions
about what I might investigate in our default kernel configuration.
Has anyone else seen anything like this? Might we be missing a sync
somewhere due to our more typical reliance on overlay filesystems?

I have been puzzled for a while.
