I now see in your /proc/cpuinfo output that apparently avx2 support is reported, but avx support is not, which should never happen. I would suspect that you have something (virtualization?) that produces incorrect cpuid output. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
