Ok. The last problem solved by rebooting the device, but i've got new issue after that. I updated the software to 6.4.0 and device became very slow.

Connected via ssh and top command displays this that kworker process uses 100% cpu

After updating to 6.4.0 it could take some time for some updates to take place. If it remains slow then you could possibly try 6.4.2 Beta 1.

Is there any way to go back to 6.2.5?

  Yes, but the process requires a factory reset - so you need to have a full backup in order to downgrade below 6.4.0.

    Ok, finally it calculated free space and everything settled down. No excessive processor usage anymore.
