Hi Marcelo, I'm not sure which v5.3 kernel you mean -- the v5.3 in Ubuntu 19.10, v5.4 in Ubuntu 20.04 or the upstream stable tree's v5.3 and newer? :-)
Here we need to make sure the 3 patches in the Bug Description are included, and also make sure the line "if (list_empty(&hbus->children)) hbus->sysdata.domain = desc->ser" in new_pcichild_device() should be completely removed. BTW, this line never made it into the upstream kernel and it only appears in some Ubuntu versions (if not all).
