Buster on buffalo NAS box: random reboots but cause unknown!

Postby jupet » 2019-01-28 09:41

Hello!

I am running Buster on buffalo NAS box (LS220DE, specs https://buffalonas.miraheze.org/wiki/Linkstation_LS220D )
The project according to which I installed the system is here: https://github.com/1000001101000/Debian_on_Buffalo

The installation went fine and Samba and SSHFS work now fine after some configuration and I had some memory
management problems but they seem to be solved now. I have documented my personal experience on this here: https://github.com/1000001101000/Debian ... o/issues/4

But the system keep restarting seemingly randomly. As far as I can see, logs contain no explanation for reboots.

Not totally ruled out but didn't see this happen on Stretch. The current system is dist-upgraded from stretch installation.

dmesg -w on ssh session had nothing interesting left on screen (though I cannot be sure if ssh session dies moments before reboot happens)

The system has no physical console/display etc.

What should I check and do next?

Now installing kdump-tools but unsure if I can figure those tools out.

I would go back to stretch and wait until the release (or the full freeze at least), it's called "testing" for a very good reason :)

Have you added any foreign sources?

I would if I actually needed the box for some actual work etc, but this is a hobby and might reveal a bug that needs to be fixed! :)

Sources list is pure debian stuff. The "wildest" line is "deb http://deb.debian.org/debian buster-updates main contrib non-free" and as far as I know the only non-free thing installed is firmware for realtek wireless which is not plugged into the box and no module for that is loaded.
