Unexplained freezes and crashes, nothing in /var/log/messages
Debian Buster here. My laptop is aging and has only 4BG Ram, however
that should be sufficient for a couple of instances of Firefox (no
streaming, etc) and an instance of Chromium.
It has happened a few times in the last few days that the system becomes
irresponsive, the screen is frozen, I can't shut X down nor go into text
mode. I can't hear any drive activity. The only way out is to shut the
laptop from the power button and reboot. I then check in
/var/log/messages and there is absolutely nothing that can give me any hint.
I thought I knew how to troubleshoot a crash but it appears I don't.
Lenovo diagnostic tools can't find anything wrong.
The only possible culprit is maybe tlp [1]? Maybe there is something in
power management that makes the laptop freeze? Or maybe the RAM is
gone/going and the diagnostic tools are not picking it up?
