For me, I've only encountered this problem when connecting from certain clients---Mac OS X 10.7 and 10.8 so far.  I can SSH to my Raspberry Pi and BeagleBone Black just fine from another RELENG_9 FreeBSD system, and from a Debian Wheezy system.  The failure mode for those that don't work is the same as reported above---a signal 6 on the server side.  Also, this hasn't always been the case, but I can't recall a revision number when the problem began.

Cheers,

Paul.
