I have recently updated my old Lenovo T520i from 32-bit F25 to 64-bit F27 and the system started freezing when actively used for a couple of hours. "Actively used" means Firefox with 10-20 tabs, some with YouTube opened, Skype and a couple of terminals.

Symptoms:

  • nothing works, the screen is frozen. Mouse is not moving, keyboard not responding, Ctrl-Alt-F2 not working.
  • mpstat 1 | tee log started previously in xterm keeps writing stuff
  • HDD light is on
  • I left it overnight in a frozen state. Didn't help: still no reaction, HDD is still (allegedly) active.

System:

  • lsusb
  • lspci
  • dmesg (this one if from the "good" system state)
  • Linux host 4.14.8-300.fc27.x86_64 #1 SMP Wed Dec 20 19:00:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

The Story:

A more or less reliable way to reproduce it is to open Firefox with a bunch of tabs (10-20) and start a long Youtube video. After 1-2 hours the freeze happens.

The first time it has frozen I've looked at journalctl and found rt-kit daemon complaining about canary thread suffocating. I thought that setting realtime-scheduling = no in /etc/pulse/daemon.conf might help. But it didn't.

The next time it has frozen at 02:25am (according to the time I saw on the screen in the morning).

Also exist chromium....

Indeed, Chromium could be an option (assuming Firefox is the culprit). On the other hand, one would think a browser should not be capable of rendering the system completely unusable...

I see a few log entries that complain about over heating on the cpu. do you need better cooling on your computer?

Yeah, I've noticed them too, but only in one log and they quickly went back to normal. Vacuumed the vent holes also...

The overheating is also a sign of aging hardware due to stress like heat or unstable electric current. If you have an excellent condition spare power adapter, try that. Sometimes it could be brittle connection at the power socket (mine actually burnt the socket but I resurrected it with a new power adapter.)
