--- Comment #1 from Michael Traxler <M.Traxler at gsi.de> ---
I just checked some more things.
It is now clear that the error is triggered by the linux kernel
version.
There are no deadlocks of the ssh-tunnel with 
5.8.15
But the deadlocks occur with 5.9.1 and vmlinuz-5.9.8.
Without understanding I speculate:
The new kernels skip some TCP-packets and this causes deadlocks in
openssh tunnels. No other application on the system with the new kernel
seems to suffer...
