That's the one with the "lazy realize" hack, right? I imagine what's happening is that we realize the GIC, and the code in this patch assumes that all the CPUs are already realized at that point. When we try to get the register value for a not-yet-realized CPU the kernel complains. (I strongly agree with Igor's review remarks here https://lore.kernel.org/qemu-devel/20251006160027.20067fe4@fedora/ that lazy realizing of CPU objects is a bad idea.) thanks -- PMM
