Looking at the problem of yours I am suggesting following patch and see whether it is working or not.
Code:

+ if (num_k8_northbridges == 0)
+ return;

this_leaf->can_disable = true;
this_leaf->l3_indices = amd_calc_l3_indices();
}
I am hoping that the above mentioned patch would help you to fix the problem of yours.
