2.4.0-test8 and ssh (OpenSSH_2.1.1): error: socket: Address family not supported by protocol

Hello,

I have just compiled the last version of the Linux kernel
(2.4.0-test8) and somehow I am no longer able to use ssh and get the
following message:

 Received disconnect: Command terminated on signal 11.

In /var/log/auth, I can find the following line:

sshd[4460]: error: socket: Address family not supported by protocol

Note that until now I have been using a 2.4.0-test7-preX with no
problem.

I do not know if the error I get is related to the following change
mentioned for test8-pre1:

    - socket() error code fix (EAFNOSUPPORT instead of EINVAL)

Thank you for your help and the great work on Linux,

Chris

Here is another connection attempt:

Upon that connexion attempt the following lines are added to /var/log/auth:
