Bug Description
Section 5.2.23.4 and 5.2.23.5 Performance Record Formats of the ACPI specification states that the length field is 16 for these two record types. Currently fwts believes this data from the firmware, however, some firmware has been known to set this to zero causing fwts to loop on the dumping of multiple records.
fwts should instead not trust this field and assume it is 16 bytes; anything smaller should be dumped out as a hex dump, otherwise it can be dumped correctly.
