boot process stops after laptop was frozen during update

Hello! My buggy Laptop Lenovo G50-30 sometimes freezes in any time I use it.

But there was not this kind of error before as the next. When I leave my laptop working on `$ guix pull && guix package -u` for a long time, it freezes with the black screen (cause the lid was closed), so only power off works. After reboot it stops on this message:

[10.800] random: crng init done

And I switch it off again and boot again, and it's ok.

The dmesg after normal boot is like this around this line:
