In theory it may make other CPUs of the same family not work in the same way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065141 Title: AMD CPU type 0x70f40 (ext family 0xa) unknown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rr/+bug/2065141/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
