Possibly - there have been some issues with em(4) and some chipsets.
Alternatively, it could equally well have been a glitch on the
associated switchport.

Logging into a client entails filesystem accesses and if any of those
filesystems are NFS mounted then those accesses will block if the NFS
server is non-responding.  Note that by default, sshd will search /lib,
/usr/lib and /usr/local/lib (as well as subordinate compat libraries)
to dlopen() nss modules - which means that a local root and /usr could
still block if you have a NFS mounted /usr/local.
