Nice, thanks for the hint, this seems to fix the problem, if we don't
use \setsansfont[]{Linux Biolinum O} (see below).

I have adapted the example to

--- 8< --- 8< ---
\documentclass{article}
\usepackage{fontspec}
\usepackage{biolinum}
\begin{document}
{\fontspec{Linux Biolinum O}\sffamily biolinum sffamily}

{\fontspec{Linux Biolinum O}\itshape\sffamily biolinum sffamily itshape}

{\fontspec{Linux Biolinum O}\bfseries\sffamily biolinum sffamily bfseries (uses oblique with lualatex)}

{\fontspec{Linux Biolinum O}\itshape\bfseries\sffamily biolinum sffamily bfseries itshape (ignores bfseries with xelatex)}
\end{document}
--- 8< --- 8< ---

and invoked

% lualatex bio.tex 
This is LuaTeX, Version 1.07.0 (TeX Live 2018/Debian) 
[...]

and got a positive result:

% pdffonts bio.pdf 
name                                 type              encoding         emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
YAQTMP+LinBiolinumO                  CID Type 0C       Identity-H       yes yes yes      4  0
FGULND+LinBiolinumOI                 CID Type 0C       Identity-H       yes yes yes      5  0
JODGAZ+LinBiolinumOB                 CID Type 0C       Identity-H       yes yes yes      6  0
FWYKIS+LinBiolinumOBO                CID Type 0C       Identity-H       yes yes yes      7  0
JFRMQG+LMRoman10-Regular             CID Type 0C       Identity-H       yes yes yes      8  0

Similar results with xelatex instead of lualatex.


Then, I've changed my current document to use

\fontspec{Linux Biolinum O}

before any \sffamily, but this didn't solve my problem.  After some
thought, I could track down the problem to \setsansfont, which my
document contains:

\setsansfont[]{Linux Biolinum O}

If I adapt above example to include the \setsansfont statement after the
\usepackage{biolinum} line, the old problem returns.  So there seems to
be some interference of biolinum and \setsansfont.

Cheers,
