So if there are any more MSI problems comming up IMHO it should be white list/disabled

We should be optimists, not pessimists.
Yes, booting on all systems is overrated anyways, isn't it?
Don't be silly. Whatever solution is arrived at will boot on all
systems. That's an obvious operational requirement.
This is how new technology always works in Linux. We turn it on and see
what works, and what doesn't. And whether existing problems will
disappear. With MSI, I think we see them disappearing.
Newer systems seem to be doing better with MSI, in part because
PCI-Express and other technologies trend towards MSI-style operation.
And the kernel's MSI code is finally getting cleaned up, and getting the
attention it needs.
MSI is useful enough that we should turn it on by default in newer systems.
That is what we've tried so far and it seems to not work.
IMO that's an exaggeration. On 50% of the x86-64 platforms (Intel), MSI
has been working for quite some time. On newer systems in the other
half of the platforms, MSI seems be more usable than it has been in the
past.
