The issue in the Launchpad report above is a bug in the PCI AER driver. We need to fix that problem, not add quirks to avoid the problem.
I think it's a pretty straightforward problem: https://marc.info/?l=linux-pci&m=145140470807043
I haven't had time to fix it myself, so it'd be great if somebody else would step up and fix it.
