Can't run KDE after upgrade

Question

I've upgraded glibsc, filesystem and migrated to systemd. I can't load KDE after it. I didn't find any info about KDE and systemd, but seems systed is the problem. KDM and initializations works without troubles, but kde plasma and desktop doesn't show up. Black screen or wallpaper and cursor is visible. Some of my daemon.log:

Probably I need to show some other log? I'm not sure which exactly.

I've dived into systemd and had some progress. One of problems was with conflict between udisk2 and udisk (both were loaded). As far as I understand KDE doesn't support udisk2, so I did systemctl disable udisk2.service. Now there are no failed units:

But it's still not working. Seems now it's dbus problem or so. What do I need to run KDE? How can I figure it out? Any wiki? suggestions?
