Hi Alejandro,

OK, that's on me then.

I have a patch for this but I can not test it for that scenario, just for the "normal" one with one port/device per IOMMU group. > I'm working on having a way for testing the first case.
Have you tried older kernel versions yet? Those seem to work for me.
> The only problem is after that, none else device hotplug can happen. I know that is not a good thing because it requires to restart the app, but better than breaking the app with a crash.
Presumably, you're only talking about VFIO hotplug, and not hotplug in general? Is there anything that can be done to fix this issue in the long run?
Thanks,
Anatoly
