Hello, everyone! I have a strange thing happening under Fedora 26. It looks like my keyboard constantly typing something. The symbol is suppressed under gnome and the only symptoms are that some text fields getting focus and terminal window scrolls down like there is keystroke but nothing appears in the input. However, I've noticed that in pure terminal "Ctrl+Alt+F3" there are symbols. They look like "^@" repeatedly appearing like I continue to enter them. But I don't. I checked that all the keys on the keyboard work as expected and no one is jammed. This actually scares me. What could be wrong?

It looks like the kernel is to blame. Booted into 4.12.4 instead of 4.13.4 and all works fine.

Update: this was a bug https://bugzilla.redhat.com/show_bug.cgi?id=1497861. It is already fixed in 4.13.5.

Kernel 4.13.5 showed up in updates this morning. That is the one supposed to have fixed the issue.
