The panic you see is a result of the new acpi_cpu driver, not ULE. In any case, it appears that acpi_cpu_idle is being called and trying to read one of the processor control registers before they are present. Please send me privately the output of: acpidump -t -d > harald-MachineType.asl
As a workaround, please set this in loader.conf: debug.acpi.disable="cpu" That will allow you to get running and give me some time to look into this.
