dom_fw_init() @ dom_fw.c
efi_memmap_walk_type(EFI_MEMORY_MAPPED_IO,
dom_fw_dom0_passthrough, &arg);
least xen reaches here.
But I'm not sure that xen crashes following line.
efi_memmap_walk_type(EFI_MEMORY_MAPPED_IO,
dom_fw_dom0_passthrough, &arg);
Although I don't remember clearly when a serial console is turned
into asynchronous mode, I suspect that the console was working
in asynchronous mode so that the log doesn't show accurate reboot point.
Could you try again with the following patch (it would be convenient
to add new xen boot options to do it) and track down more?
