Thank you for caring. I followed the advice in https://askubuntu.com/questions/971477/ubuntu-17-10-keeps-locking-up- and-freezing-mouse-and-keyboard-input-doesnt-wor and added this to my /etc/default/grub:
quiet splash intel_idle.max_cstate=1 The system is stable since then. According to https://gist.github.com/wmealing/2dd2b543c4d3cff6cab7 using cstate 1 might be a bit paranoid, so I will experiment with the maximum reliable value. Sorry I cannot test the upstream kernel, because I need the nvidia driver/cuda combination for my daily work. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1777311 Title: System freezes randomly Status in linux package in Ubuntu: Incomplete Bug description: System freezes randomly on a daily basis. First the mouse pointer actions are getting slow for a few seconds and after that the screen freezes. Various SysCtl key combinations I found on the net do not work. Switching to a console does not work. Remote login via SSH is not possible. The only way to get the system working again is a hard reboot. I did not find valueable information in the log files indicating what wents wrong here.
