I have tried to run fresh build net-next, for some reason the build
stops ssh service from starting up, tried 3.7.0-rc4 too, same issue. I
don't know if it is new kernel bug or ubuntu upstart bug, but that is
another issue.

Not sure Ubuntu 10.04 binaries can run a 3.7 kernel.

Some bug fixes in kernel need bug fixes in userland.

You could try a bisection ?

 I saw the same issue with Ubuntu starting around 3.7.0-rc1 but 3.6
was fine if I recall. (I did a partial bisection but was not sure it
was a kernel issue)
 sshd would not start up on boot and I 'fixed' it by adding the
following in /etc/rc.local since I assumed it was a userspace issue.

if [ ! -d /var/run/sshd ]; then
   mkdir /var/run/sshd
   chmod 0755 /var/run/sshd
fi
/usr/sbin/sshd
