Hmmm ... that looks grim - the error comes from here, in the
XFS kernel code (xfs_mount.c):

        if (sbp->sb_dblocks == 0 ||
            sbp->sb_dblocks >
             (xfs_drfsbno_t)sbp->sb_agcount * sbp->sb_agblocks ||
            sbp->sb_dblocks < (xfs_drfsbno_t)(sbp->sb_agcount - 1) * 
                              sbp->sb_agblocks + XFS_MIN_AG_BLOCKS) {
                cmn_err(CE_WARN, "XFS: SB sanity check 2 failed");
                return XFS_ERROR(EFSCORRUPTED);
        }

So, it seems mkfs might be coming up with bad data.. haven't ever
seen that before.  Could you run xfs_db on the device, and print
the superblock & send us that?  Something like:

        # xfs_db -c sb -c p /dev/foo

and we should be able to narrow it down to one of those 3 condition.

thanks.
