I had called it, but didn't spot the problem there. I don't remember exactly what the output was, I had expected to see some process show a large value in the IO column, but that was not the case. I THINK! Various processes appeared, mostly Akonadi stuff. I should have logged this, I don't remember this s well. I have caught some illness, and had fever, which did not help my memory. There were some kworker processes listed on top, but I don't remember whether in iotop or in top. Hmm. Now I just started Akonadi again, and get a lot I/O in iotop, and xosview again shows much iowait CPU activity for a while. But that calmed down after a minute. > I'll write more when I get some time to think Thanks :) Wonko
