This in-kernel change fixes the stabiliy issue you have encountered but at the cost of performance. And for people like me, whose CPUs are not affected it is even worse. We lose performance for just nothing. IMHO the proper way would be if AMD would off= er a CPU swap for affected customers. --=20 You may reply to this email to add a comment.
