Comment 9 for bug 1799397

Suspicious sequence is in most, functions reported to be broken - but it is not identical to what is reported upstream:

here with avx512f disabled

But since it isn't exactly the same as reported it is too unreliable and I don't have skylake+mlx5 card I can't test for it by compiling alone :-/
