It is not possible to use SSE and AVX extension. I tried to reinstall from the zfs repo. Everything is up to date.

What is going wrong here?

This is a known issue (#8965 but beware, there is a further fix required before it should be used).

For now I recommend patience.

It should there in future update for fedora.
Mine shows:
