Thanks for reporting this issue.

Looks xen_start_info is NULL in code "pmbits = (xen_start_info->flags & 
SIF_PM_MASK) >> 8" in xen_acpi_processor_extcntl_init(). It is abnormal that 
xen_start_info become NULL.

Could you share more info on your configuration, so that I can reproduce it? 
E.g. is it 32bit dom0 under 64bit hypervisor? Also do you mind attach the domi0 
.config file?

Best Regards
