After adding pci=use_crs to the kernel command line, no more trouble. Ok, we can add a quirk. dmidecode output reveals that this is an MSI MS-7253, for which we already have a quirk, but the short-sighted author tied the quirk to a single BIOS version, making it not kick in on Carlos's machine with BIOS V1.2. If a later BIOS update makes it no longer necessary to look at the _CRS info it will still be harmless, so let's stop trying to guess which versions have and don't have accurate _CRS tables.
