My guest boots with your .config and SNB as CPU model:

..
[    0.373770][    T1] smpboot: CPU0: Intel Xeon E312xx (Sandy Bridge) (family: 0x6, model: 0x2a, stepping: 0x1)

Artefacts like:

-initrd initrd-vm-meta-180.cgz

or

RESULT_ROOT=/result/boot/1/vm-snb/quantal-x86_64-core-20190426.cgz/x86_64-rhel-8.3-bpf/gcc-12/48204aba801f1b512b3abed10b8e1a63e03f3dd1/3

I don't have and don't know how to generate here so I can't run your
exact reproducer.

Thx.
