Slow boot due udisks2.service

Hello,

on new Leap 42.3 installation the boot is extremely slow, main issue is udisks2.service - about 30 s, see the list below.
I have 3 HDD’s - 1) 2TB monted as /home and 2) SSD 120 GB with operating system.
3) Another SSD 120 GB with Windows 10, there is no booting issue on Windows.
Any idea what can be the rootcause?

Many Thanks

Tomas

Nothing depends on this service normally so its startup time hardly matters. “systemd-analyze critical-chain” is usually more useful in this case.

The critical chain shows following list, the real boot time from boot menu until GUI is ready is about 50s:
