Thanks, there are versions of backend libraries I need, so it is helpful.
ALso it proves that for unlocking crypto works.

It is failing the benchmark here, so there is probably another bug in benchmarking.
What CPU is that? Is it some very fast machine? (paste lscpu output if possible).

What is number of iterations for the used slot? - you masked that out in the
first mail.

I need to either reproduce myself or I have to add some more debugging output
there.

If I add some debugging code, can you compile it and run it on your hw?
(Or I can provide debug binaries if you prefer that.)

Thanks,
Milan
