I was trying to reproduce it on Dual Xeon (HTT enabled) without any luck.
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.

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.
