You're right, the vendor could have disabled AES-NI by intention - but they offered this box especially with AES-NI capabilities. See here: http://freebsd.1045724.x6.nabble.com/r285947-broken-AESNI-support-No-aesni0-on-Intel-XEON-E5-1650-v3-on-Fujitsu-Celsius-M740-td6028895.html I feel a bit pissed off right now due to Fujitsu, because we started testing some encrypting features and I'd like to use AES-NI and I run into this issue again. I need to know that FreeBSD is not the issue with this specific CPU type. I'm still frustrated by that stupid comment "UNIX is not supoorted" I got that time then when I reported 2015 the issue to Fujitsu. -- O.
