miscellanea/cpuid fails with unusual output

[rodwsmith]

Bug Description

In a recent submission, the miscellanea/cpuid test failed with the following output:

CPU Model: Intel(R) Xeon(R) 6766E
Unable to determine CPU Family for this CPUID: <__main__.CPUID object at 0x715cff1b7530>

This looks like it may be a problem parsing the output of this CPU's information, but I haven't fully traced it (and might not be able to without access to a system that shows the symptoms).

The relevant certificate request is:

https://certification.canonical.com/certificates/2409-16076/

To Reproduce

1. Run certify-ubuntu-server (or presumably anything else that causes miscellanea/cpuid to run) on an affected system (Intel Xeon 6766E, presumably; maybe others...?).

Environment

• Ubuntu 24.04
• Intel Xeon 6766E CPU

Relevant log output

CPU Model: Intel(R) Xeon(R) 6766E
Unable to determine CPU Family for this CPUID: <__main__.CPUID object at 0x715cff1b7530>

Additional context
