This may be a long-shot, Per, but does failed DNS have anything to
do with this? I've seen v4 hangs when DNS wasn't available,
there's even a phrase to turn off DNS look-ups in sshd_config.
Sometimes I've also seen issues with X or agent forwarding. In doubt
I would try to disable them explicitly, (ssh -xa ...). You may also
try non-interactive login for testing:
ssh -4 -xa remotehost true
Tnx Rudi - didn't do much good. I'd already tried disabling X
What I don't understand is - why should any issue _only_ affect IPv4?
It's really weird.
