System: Laptop Ryzen 2500U 8GB RAM Lenovo ideapad 330-15 ARR Description: Ubuntu 18.04.4 LTS Release: 18.04 apt-cache policy linux-image-5.3.0-53 linux-image-5.3.0-53-generic: Installed: 5.3.0-53.47~18.04.1 Candidate: 5.3.0-53.47~18.04.1 Version table: *** 5.3.0-53.47~18.04.1 500 500 http://ar.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 100 /var/lib/dpkg/status linux-image-5.3.0-53-lowlatency: Installed: (none) Candidate: 5.3.0-53.47~18.04.1 Version table: 5.3.0-53.47~18.04.1 500 500 http://ar.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages Symptoms: The system will lock right when it should shutdown or restart. The screen goes blank (but monitor doesn't turn off) and keyboard becomes locked up (i.e. numpad LED still lit, but will not respond). Only solution is to keep holding Power down for 10 seconds. Attached core dump from lightdm which seems to be generated with the crash.
