Thanks for the hint. I saw it already and just contacted Realtek
whether they are aware of any MSI-X issues with particular chip
versions. With the chip versions I have access to MSI-X works fine.

There's also the theoretical option that the issues are caused by
broken BIOS's. But so far only chip versions have been reported
which are very similar, at least with regard to version number
(2x VER_40, 1x VER_39). So they may share some buggy component.

Let's see whether Realtek can provide some hint.
If more chip versions are reported having problems with MSI-X,
then we could switch to a whitelist or disable MSI-X in general.
