Yeah, it looks like the call to irq_desc_get_handler_data() inside that irq handler is returning null. But I don't understand most of that code, so no idea what might be causing that.
As a side note: From the looks of it it's probably not going to be relevant, but just in case it is I have dumped the contents of the memory region which is returned by the _CRS method of the AMDI0030 ACPI device.
