Keyboard does not work after suspend

I am using Ubuntu Budgie 17.04 on Sony Vaio and I have the following issue with "suspend" functionality: after resuming from suspend, the keyboard does not work anymore, it is powered but the keys do not work, I am forced to reboot the system.

In system log /var/log/systemlog the following messages can be found:

May 20 10:24:01 erica-SVF1521C4E kernel: [ 938.182088] i8042: Can't write CTR while closing AUX port

How to solve the issue?
