$ sudo mkfs.xfs -f -mcrc=1,finobt=1 -m crc=0 -d size=128m /dev/ram1

^^^^^ ^^^^^^^^
.....
$ mount /dev/ram1 /mnt/scratch
[ 4727.269080] XFS (ram1): Mounting Filesystem
[ 4727.270077] XFS (ram1): Log inconsistent or not a log (last==0, first!=1)

If "-mcrc=0" is seen on the command line, it needs to turn off
finobt....
xfs/001 and xfs/002 trip over this when run like:
$ MKFS_OPTIONS="-mcrc=1,finobt=1" ./check xfs/00[12]
Otherwise, everything seems to be working ;)
Cheers,
Dave.
