rcu_sched self-detected stall on CPU

[davidak]

The system was unresponsible for 8 minutes, screens completely frozen, can't even move the mouse. I havn't done anything unusual. Using Chromium, Terminal and Atom.

It is now the third time this happens and actually a problem to use this system at work!

Can you help analyse this problem? Is it a software bug and can be fixed or a hardware problem and the notebook needs to be replaced?

Still using older kernel since newer versions have a bug where wifi don't work.

The system clock was frozen at 15:39 today (09.08.2017).
