So I can confirm the behavior with a local Xen Server and a HVM Xenial guest. While the current proposed 4.4 kernel crashes while setting up the acpi interrupt, this does not happen with a 4.15 kernel from proposed on a Bionic HVM guest. Still I was able to get the 4.4 kernel to boot by reverting the following patch. Despite it being applied to 4.4 and 4.15 proposed. So it sounds like something outside the scope of the patch itself that changed between 4.4 and 4,15 is causing the problems.

    XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information.
