Bouts of Slow Response on Teres Ubuntu 20

Recommended Posts

I'm on the Olimex Teres running the newish Armbian Ubuntu 20.04 and I'm having a lot of trouble with the system intermittently freezing or slowing.  Kernel 5.4.43 .  I have a video of the issue and an image of the drive.  The system isn't online to sync clock and dates may be skewed by some days.

 

My usual routine is to boot the system into multi-user, run asciinema, run tmux, and then edit files with vim inside both.  The issue starts after a bit.  CPU and I/O usage stay low during the delays in responsiveness.

 

Sorry if I am kinda irritated and frustrated in the video.  I've been dealing with a lot of issues.  I'm curious what systems the maintainers use, to see if they would be more stable options than the Teres.  Here are the files.  The first one is the video.

I tried using apt to upgrade the system but the problem was still present.

I tried downloading the latest release of focal from armbian and running this from a microsd card resolved the brunt of the issue.  I notice the kernel is newer than the one apt gives and made a separate forum post regarding this.

wonder if you're running into the back to the future bug on A64...
