@yllar @mik @Pilow @marcvds Hello, we think we now understand better this issue.
We think it's a Xen issue with regard to PCI devices on segment 0001 (which is your case) and not a dom0 driver issue.Could you give a try to this ISO installer please?
Please note that this is a custom test ISO and it is therefore not officially supported, do not use it for production, it is just to confirm that it fixes your issue, we will release a supported ISO in the future (target date for now is June).unsupported test ISO for you to test: https://nextcloud.vates.tech/index.php/s/iHf8sqq39EqE683

Has this been fixed by the update described here?

@yllar I'm not sure honestly (I will have to ask the rest of the team), but anyway, even if it were fixed by latest xen package, we still didn't publish a new installer ISO with the fix.
Target is still around June for the new ISO.

@yllar I'm not sure, maybe it'll slip to July.
But what I can say is that the ISO is currently being tested in our QA process.
Brace yourself, it's coming soon

@yllar Hello,
We are still validating the ISOs, but we are getting closer to releasing them.
We hope to make them available soon.
