Per https://bugs.freedesktop.org/show_bug.cgi?id=111122#c25 it seems that Lenovo released a BIOS update (1.54 / R0UET74W) to fix IVRS tables on E485. As the Ideapad 330S-14ARR and 530S-14ARR use the same mobo, I guess it is also fixed there (or going to be fixed soon).
Will the BIOS fix interfere with the kernel patch?
