Hi Benjamin, > Fengguang, > > I ran your script against freshly-checked-out source from staging-next, and was not able to reproduce the error with it. My boot log is attached. I noticed that your log did not have "Hypervisor detected: KVM" in the trace. The KVM options in your script also differ substantially from the ones shown at the end of your trace... > When I reran your script with the "-cpu Haswell,+smep,+smap" option I was able to get the same result as you. IMHO KVM should not be setting this bit if it's emulating bare metal. Sorry.. We tried to provide a simplified reproduce script and in your case, it has a significant mismatch with the real KVM options. We'll fix it, thanks for pointing it out!
