Relation "storageadmin_pincard" does not exist (following upgrade from 3.8 to 3.9.1-2)

Coming back. I’ve tried to install RockStor 3.9.1 several times, but the installation process fails on boot with sympthoms described at this thread:

Key three error messages at the installation log are:

*ERROR* timed out waiting for Punit DDR DVFS request
dracut-initqueue[565]: Warning: dracut-initqueue timeout - starting timeout scripts
dracut-initqueue[565]: Warning: /dev/root does not exist

My hardware is a GigaByte GA-N3150N-D3V motherboard and SanDisk UltraFit USB3.0 key (however, installer fails even without plugging USB key).

I’m blocked for the moment.
