I think I found the reason = this works on Intel (the CPUID feature bits where SPEC_CTRL would be indicated a= re cleared) and not AMD (on AMD, we pass through those feature bits from the host). Both Intel and AMD share the same SPEC_CRTL MSR and we do not imple= ment it on either platform. Please try the committed change, I believe it should fix the issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
