DEBUG_IRQ revealed no real news for me, except for the fact that IRQ 10 was discovered, but apparently no interrupt came in, handle() was not called once. So I added acpi_drv to my setup, resulting in a different log. As you suggested, I attached the new log as well as my configuration file. Another interesting fact is that, when the iommu flag of the hypervisor is removed, it looks quite different already. A log file of this behavior is also attached. Regards Markus
