I now run
[spinymouse at archlinux ~]$ jackdbus auto  
no message buffer overruns
no message buffer overruns
no message buffer overruns
Then I launched QjackCtl. I had to start Jack with QjackCtl again,
"Enable D-Bus interface" was checked.

The output:

It's running, btw. I didn't connect or disconnect a client.

Hm? I guess I'll compile Jack2 classic later and see what will happen,
perhaps I should build an older kernel too.
