So I found a box exactly like yours:

[    3.699583] smpboot: CPU0: AMD EPYC 9754 128-Core Processor (family: 0x19, model: 0xa0, stepping: 0x2)

and it updates just fine and just like on yours:

[   28.457381] microcode: Current revision: 0x0aa00215
[   28.462827] microcode: Updated early from: 0x0aa00215

The next thing that is catching my eye is your simulated NUMA config:

[    1.668943] smp: Brought up 32 nodes, 512 CPUs

Lemme see if I can repro that here.

Thx.
