I manually backported the following patch: 6efa20e xen: Support 64-bit PV guest receiving NMIs --- a/arch/x86/xen/enlighten.c +++ b/arch/x86/xen/enlighten.c @@ -427,8 +427,7 @@ static void __init xen_init_cpuid_mask(void) =20 if (!xen_initial_domain()) cpuid_leaf1_edx_mask &=3D - ~((1 << X86_FEATURE_APIC) | /* disable local APIC = */ - (1 << X86_FEATURE_ACPI)); /* disable ACPI */ + ~((1 << X86_FEATURE_ACPI)); /* disable ACPI */ and my issue is completely fixed. Should it backported for stable?
