But now I have a problems with openssh.

When I run first "openssl speed -evp des -elapsed -engine cryptodev"

I got:

but when I run ssh without running openssl speed before I got the freeze 
in ixp_q_process.

Do you use some patch for ssh too? I found some patches which adds some 
  openssl engine initialization to ssh but it won't helped.
