I even added '-engine cryptodev' to openssl command, so not only ssh/sshd can use it, but still nothing. I heard about bugs which exist only on real quad processor machines (where dual xeon with HTT isn't enough). This could be one of them. +> Is the hifn driver perhaps not fully smp safe ? Could be... Actually, when I was reproducing this lock up, I was able to enter ddb and you said it locks up hard for you? This could be another issue then. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
