Some program might be trying access hardware directly

Hello.
After my upgrade of Whonix-Gateway I got messages like this:
[ 1162.578855] atkbd serio0: Spurious NAK on isa0060/serio0. Some program might be trying access hardware directly.
I’m thinking it’s not very safe. What can I do with this?

Nothing to worry about:
