This is wrong at many levels: - we shouldn't have two VMSTATEDescriptions with the same name - In case this is the only solution that we can came with, it needs to be: * register pre_2_10_vmstate_dummy_icp * unregister pre_2_10_vmstate_dummy_icp * register real vmstate_icp As the initialization of this machine is already complex enough, I need help from PPC maintainers to fix this.
