Ubiquity if start install process, but for few seconds stop installation and use 100% 1core CPU

[Rovano]

If Ubiquity start installation process and format target partition on HDD(manual adjustment of the layout), Ubiquity eat my 1core and stop install process.
I've yet tested other options.
My system have 1SSD(not target for installation process&3HDDs).
