Both system has CLFUSH and SS, so CLFLUSH tweak should not executed.
Can you test with these patches? Testing on only one of both system
is enough. "patch-1" forces disabling CLFLUSH feature even if SS bit
exists. "patch-2" forces no CLFLUSH tweak. I'd like to know with
which patch your system can live.
