Did you regenerate the root cell config after adding the card? Or manually added
the additional entries needed for it? Something went wrong in that area.

I regenerated the config and cross checked with the working one.
Nothing vicious was found.

I did notice that the IRQ was an IO-APIC IRQ in the /proc/interrupts.
I think this is the problem. I am working on a MSI version of the driver.

Conceptually, IO-APIC-based interrupts should work as well (and do in other
setups).
In this case, do I need to add irq_chips to the sysconfig?


The config generator adds all IOAPICs that are reported via ACPI to the sysconfig as irqchips.

And if they do not work, you should at least see some error messages on
the hypervisor console. Do you?

No I got nothing. The initialization finfshed happily without errors.


Could you share the data tarball that "config collect" aggregates?
