Running Kubuntu 9.1 x64 all updates/fixes

Plasma crashes occasionally, restarts 95 % of the time (fast). Other 5%, desktop is black but window effect ( in german "Arbeitsflaechenumschalter / Raster" ) on my 4 desktops works.

Did install Nepomuk server/client as stated on the kubuntu homepage when trying kde 4.4 rc2.
Nevertheless gives me a hard time. starts, doesn't activate index search (says itself).

Kontact seemed to not have worked till i figured out that akonadi server (with internal mysql in my case) is not running. Now i have to load akonadi manually at startup (or with systemsetting startup) and start the server again manually before being able to read my email.

System Load overall increased.. something happened to the sound system which i can not identify.
When running wine - Civ 4 bts , i get multiple sound output, system drastically slows down (which hasn't happened before) and desktop effects deactivate after a while with nearly no improvement in performance.

Strangely despite above. The overall "feel" improved,
