Re: [Nix-dev] Unwanted, unannounced reboot

[Alexey Shmalko]

I've experienced spontaneous reboots too, though they only happen after I 
update my NixOS. This doesn't happen immediately but rather when I'm away from 
keyboard some time after.

Re: [Nix-dev] Unwanted, unannounced reboot

[Matthias Beyer]

Wow.

Thank you _SO MUCH_ for reporting back.

I really hope that it is a software issue, I really do not want to 
repair hardware or smth like that, so if this is really a software 
issue it is annoying but I can live with that, because software errors 
are way cheaper to fix. :-)

Same here, yes

I had Archlinux before (beeing on NixOS for 1,5y by now) and never had 
this issue, but well, that was before kernel 3.18 or so, so maybe it 
is a new kernel issue...

I'm not sure whether to report to LKML, though.

Re: [Nix-dev] Unwanted, unannounced reboot

[Matej Cotman]

I have X220 and suffer from exactly the same problem, I had it at official
thinkpad service for 2weeks or so... just to be sure, they put it through
all posible tests, the laptop worked flawlessly - they did not find
anything wrong with hardware. This reboot event happens every few months or
so, some times even same day. Nixos is the only distro that lived on that
laptop. But since there are little or no reports of this on internet,
ubuntu should work(?). My guess is that some kernel switch is not set
correctly. I have tried a lot of stuff, even switched to another SSD. What
i havent tried is to make diff of ubuntus kernel config and nixoses and go
from there but since reboot happens every few months... you do the math..

Re: [Nix-dev] Unwanted, unannounced reboot

[Jeffrey David Johnson]

I have a probably-unrelated issue, but mentioning it just in case. Mine 
involves VirtualBox. When starting up I will log in and open my email or 
something, but in the background the vboxnet0 service will be failing to start 
via systemd. When it times out after 90 sec the X server is killed without 
warning and I'm back at login.

One of my machines (a model different from yours) would turn off at
random times.  I "solved" the issue by pulling the battery out and
leaving the laptop on AC power all the time.  Apparently, I have a badly
built machine :-)

You could perhaps try a similar experiment and see what happens.

I don't think it is overheat. My device is at ~56-60 °C all the time, 
sometimes up to 70°C when doing compile jobs or such things, and it is 
rather warm here anyways, but I wouldn't say it is overheated.

But if xfce triggers a shutdown, this causes some shutdown of 
processes, log messages by systemd and so on... in my log is 
_nothing_.

The chromium messages are probably unrelated, they happen all the time
here too (due to some sandboxing issue I think, plus over noisy audit
subsystem)

Just a wild guess: there's lots of chromium-related messages in your
