The symptoms very closely resemble that of the Lenovo issues with NVME resume. Lucienne was released in a similar timeframe as the Renoir / Cezanne Lenovo laptops and they may have similar BIOS code. Applying the same quirk to this system allows the system to work with IOMMU enabled and s2idle resume to work.
