This is highly unlikely to be an upstream kernel bug. The unwanted probing= is most likely coming from elsewhere. Given that the out-of-tree VirtualBox driver loads shortly after the failed kvm_amd.ko load, my guess is that vboxdrv is= the culprit.=20 [ 3.087169] kvm_amd: CPU 1 isn't AMD or Hygon [ 3.118021] vboxdrv: module uses symbol (cr4_read_shadow) from namespace module:kvm,kvm-amd,kvm-intel, but does not import it.
