This isn't an example of a per-device breakage, though. It only shows up on some devices, but the cause is apparently the chipset. Those devices work fine on other boards.
As mentioned later, it appears that CRS stuff might be related to this problem, but if it couldn't be fixed, I think the only sane solution would be to blacklist MMCONFIG support on that chipset.
