Host reboots spontaneously with HAOS =>16.1

[auanasgheps]

Describe the issue you are experiencing

Hello,
I have been noticing a weird pattern on my host: it reboots spontaneously, from time to time. It can be 1 day, 3 days or 1 week.

I have seen this pattern with HAOS 16.1, 16.2, 16.3. Each of these versions has some degree of reboots, which I track using "System Monitor Last boot". I am sure this host did not do this in the past and be up until the next OS upgrade.

To be noted: when it reboots, it starts up successfully.

I've checked both supervisor and host logs (journalctl) and I could not find anything relevant. I've attached the last reboot logs (host logs are one hour behind)

The host is hardly used at all: RAM, CPU usage and temperature are all absolutely normal. No manual task is running on the host at the same time.

I don't know what else should I look for. Am I missing something?

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

16.1

Did the problem occur after upgrading the Operating System?

Yes

Hardware details

Acer Chromebox CXI3 running a UEFI BIOS (MrChromebox)
Intel i3 8130U, 4GB RAM, 128GB SSD.
USB Devices:

• Sonoff Zigbee ZBDongle-E
• USB UPS managed with NUT add-on
• mmwave sensor Everything Presence Lite
• Broadlink RM Mini 3

Steps to reproduce the issue

Just wait for the system to reboot for no apparent reason.

Anything in the Supervisor logs that might be useful for us?

Additional information

I thought that the issue could be caused by a legacy add on, Google Drive Backup, which you see installed. However it's turned off since I migrated to the native backup solution.

[tzdisco4]

I encounterd today by chance that the OS of my HA installation was rebooting automatically, because the GUI got unresponsive from one second to the next. I immediately logged in as root and saw that it was currently booting,

I checked journalctl and found entries since October 30 showing segfaults of several programs/services including kernel starting from November 16 up to today. I found 114 segfaults. Before that date none.
It is obviously related to a HA OS update from 16.2 to 16.3 that I had carried out on November 14.
Currently running HA Core is 2025.11.2

# uname -a
Linux homeassistant 6.12.51-haos #1 SMP PREEMPT_DYNAMIC Tue Nov  4 13:52:04 UTC 2025 x86_64 HAOS

This makes me wonder as the OS update was numbered 16.3. It is running in a virtual box on an Ubuntu System (intel NUC I5).:

tz@smart-nuc:~$ uname -a
Linux smart-nuc 6.14.0-35-generic #35~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Oct 14 13:55:17 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

I attach a file containing a "grep -A 3 segfault myjournal.log > segfaults.log".

Before the OS update HA ran stable for months. If further information is needed feel free to ask.

segfaults.log

Log of reboot today:

[auanasgheps]

At least you have some sort of error, the first three lines tell that something is going bad.
In my case I literally have nothing 😥

[tzdisco4]

Indeed this is a difference. We'll see whether there will be some feedback from the maintainer team. If not I think I should create a new issue describing my specific case.

[auanasgheps]

The host has entered a phase of too many frequent reboots. The logs, as before, are telling nothing.

[sairon]

Have you tried if downgrading to an older OS version remediates the issue? If not, then it might be a hardware issue, faulty power supply is one of the most common causes.

[auanasgheps]

Have you tried if downgrading to an older OS version remediates the issue? If not, then it might be a hardware issue, faulty power supply is one of the most common causes.

Three days ago I've downgraded to 16.x which I'm sure was stable because it's from the summer period. I'll report back after I surpass 1 week of uptime, which is the best I've had with 16.1.

If it reboots earlier, I'll replace the power supply!

[auanasgheps]

After 8 days with HAOS 16.0, it rebooted again. It happened again during the middle of the night at 4:12am. This is suspicious as most of the reboots happened between 3 and 5am.
Nevertheless I'll be looking at a replacement PSU.

[bcutter]

during the middle of the night at 4:12am

Maybe just a conicidence, but this time matches the auto purge recorder time. Maybe check HA (not HA OS) logs additionally.
