Ten cents says that you have discovered that AMD returns a synthesized value for XINUSE[PKRU] and that write_pkru() is buggy.
Any volunteers to fix the if (!pk) case in write_pkru() and see if the problem goes away? (Or at least to print something for the if (!pk) case and seee if it gets printed?)
