Strange cyclic freezing with Zyxel NAS326 (no replies)

After last update to Linux Kernel 6.5.7 I got a strange problem. Now I run Linux debian 6.4.11-mvebu-tld-1 as I tried to downgrade to see if it would get better.

When I am connected via SSH I can write about 5 seconds, then it freeze for about 10 seconds, then it spits out what I have written and I can write about 5 seconds more before it freezes again. From time to time I get "client_loop: send disconnect: Connection reset". Then I have to reconnect, and it takes time as it seems to freeze there also. It is like it has very much to do, but I cant see that it is doing anything special.

BUT if I connect to it with a terminal and run:

ping 127.0.0.1

And I let the ping command run. Then I connect to it with another terminal, then suddenly it is fast and normal.

Does anyone have any guesses as to where I should start looking.

I have tried adding the following line to the /etc/ssh/sshd_config file an rebooting it, but it didn't help.:

UseDNS no
