It appears to have been a change in the kernel.

One of the above files is probably the culprit.  I did notice that a recent
commit upgraded IPFilter to 3.4.16, so perhaps that is where the problems
began.  They are fixed now.  I just cvsuped and found that only the kernel
code changed.  So, I just built a new kernel - all is now well with SSH1.  I
am curious what about SSH1 was sensitive to a kernel change but SSH2 was
not.  Incidentally, I am currently using IPFilter.

Nope..

I wonder if you were having transient DNS problems which just happened
to coincide with this.  DNS is the big thing which causes OpenSSH to
have problems.
