Filing a note here in case I forget later.

It looks like GRUB in 14.10 doesn't support XFS's new on-disk metadata format that has CRCs. (rationale: https://www.kernel.org/doc/Documentation/filesystems/xfs-self-describing-metadata.txt)

redhat bug with some patches from Dec 2014:
https://bugzilla.redhat.com/show_bug.cgi?id=1001279

I haven't yet dug up any changelogs about those patches getting merged into GRUB's upstream git repo.

If there's a PPA, or an easy way to build a .deb from git master (or some other way I can easily test git master on an Ubuntu system), I'd be interested and willing to test this.
