Comment 301 for bug 1690085

There's a lot of amd bashing in this thread, I'm still inclined to believe that it's just bugs to work out with a new major CPU changeup. The same kind of bugs bubbled up when athlon 64 + opteron came out.

Beyond the idle bug (which does indeed seem fixed so far adding the rcu_nocbs boot flag), performance seems fine under Fedora 27.

Let me ping my amd graphics contacts and see if they're aware of this ticket.
