I found that gzip'ing the image makes it small enough to attach to this bug. So to replicate the problem under -28, download the attached file and do the following:
d3m406@nitwo-ubuntu:/tmp$ gunzip < ~/Desktop/100mb.xfs.gz > /tmp/100mb.xfs
d3m406@nitwo-ubuntu:/tmp$ sudo mkdir -p /mnt/100mb
d3m406@nitwo-ubuntu:/tmp$ sudo mount -o loop /tmp/100mb.xfs /mnt/100mb
