Follow-up Comment #1, bug#65020 (group octave):

It is most likely OpenBlas issue. 
Can you repeat the test on Xeon preloading reference blas library?
Start octave as:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/blas/libblas.so.3 octave

You can try to download and compile the latest openblas library and preload it
the same way. It should also help with performance, your Xeon is probably too
new for your Openblas library (and it uses some generic kernel instead).
