[Nouveau] known MSI errata?

[Lucas Stach]

Hi,

recently we tried to enable MSI interrupts with nouveau. Unfortunately
there have been some reports of things failing with certain cards, where
it isn't entirely clear if this is a GPU errata or some other component
in the PCIe chain failing.

Could you perhaps investigate if there are any known Nvidia GPU erratas
with regard to MSI interrupts, or maybe tell us the generations of cards
that are generally safe to enable MSIs with?

Thanks,
Lucas
