VM images for 12.0-CURRENT showing checksum failed messages

[David Boyd]

The FreeBSD-12.0-CURRENT-amd64-20171012-r324542.vmdk image displays
many checksum failed messages when booted. (see attachment).

I think this started about 20170925.

I have VirtualBox VM's running 10.4-STABLE, 11.1-STABLE and 12.0-
CURRENT.

Only the 12.0-CURRENT image exhibits this behavior.

This is easily fixed by "fsck -y /" in single-user mode during the boot
process.

I can test any updates at almost any time.

Thanks.

David Boyd.
