I was using my laptop normally, suddenly my super key didn’t work. I tried to reboot and hope it can solve the problem. However, my laptop just stuck with a loop spinning on my screen forever. I pressed esc and a bunch of orange log with few red lines like “cpu#N: lockup … 851s…” are shown. Finally, I decided to force shutdown the laptop and boot it up to run journalctl -b -1 -p err and found following messages.

the super key still doesn’t work after boot up.
what should I do to repair my computer? maybe reinstall nvidia drive?
I’d really appreciate any help or ideas.
Thanks a lot!
