LIME2 Rev.L lock-up freeze instability

[faraz]

So, more people are facing the same issue. I am not alone.
What solved my problems partially, was I masked the reboot and shutdown commands.
I have good uptime on one site and issues on the other.
Not sure what revision board is on the site that's been up (uptime almost a year now). The site that's going off is using Rev L boards.

I am going to implement the scaling option suggested above and see if that helps. and also learn how I can configure a watchdog to reboot the system.
I am also logging current_now, voltage_now and Temperature_now values.

Do you boot from the eMMC?

Can you check what is the revision of the stable board?

Is your Linux image based on Olimage?

How do you power the board and do you have a Li-Po battery?

Differences between revision K and latest L1 had been quite significant. Most notably the eMMC and the RAM are different, so it is probably something about support of those two in your image. You can check hardware changes here:

I can confirm KriszK solution.
We had the same freeze problem, but changing the governor to peformance solved
the problem.
