Shutdowns due to overheating

frediz · November 19, 2022, 8:28pm

Hi,
since a few weeks, my L5 shuts down “properly” itself “randomly”.
Sometimes several times a day, sometimes not.
Checking the logs, this is due to :

thermal thermal_zone0: cpu-thermal:critical temperature reached, shutting down
reboot: HARDWARE PROTECTION shutdown  (temperature too high)

Needless to say it’s both worrying and annoying when you’re not notified and you think your phone
has just stopped its display whereas it’s just off not able to ring, and when you have to
start it and enter 4passwords to have it active again.
Even more worrying (for me at least ) when I don’t see anyone mentioning that in the forum.
I’ve not noticed it each time it happened so couldn’t check how warm it was,
but some time, 10-15mn after, I found it cold, not even warm.
I didn’t have time to investigate like dumping temperatures and top cpu intensive processes
on a regular basis.
I also got the impression this behavior started to happen after kernel 6.0 upgrade. I didn’t remember
having that even a single time since I have it.
Most of the time my cpu is around 34°C. Seems that critical temps is set to 95°C (/sys/class/thermal/thermal_zone0/trip_point_2_temp) which is really high.
I’ve got no particular software installed. I notices packagekit and gnome-software sometimes wake up
and eat a lot of cpu for a bit of time, but they seem to stop after a while.
I use my L5 more like a phone than a computer, meaning no intensive use, just a few calls and messages, no data connection, no firefox (tried it once on youtube and after 20mn the phone was really
warm and did not shut down btw)
One point is I use a thin leather sleeve… The temperature at home or in my car, is
usually below 20°C and the sleeve may keep it a bit warmer, but there’s no fan in the L5, so, I don’t get
how the sleeve could prevent cooling in November with low indoor temps to the point it reaches 95°C.
It also happens without the sleeve.
So really light use and never really warm.
Any thoughts ? I’ll try dumping some info in syslog to finally investigate.

Ok,
I had just wrote a script to try log some details and enabled/started it
as a service and it did it again.
No sleeve on. Kitchen temp was low and my L5 was sitting on the table idling.
No details dumped only this :

This continues to happen. And having a look to the details I noticed that different thermal_zones are
triggered. And my script missed that.
So I did some archeology.
I received my L5 on October 4th, 2022.
Got my sleeve October 11th 2022.
I see a total of 125 boot logs :

Kernel 6.0.0-1-librem5 was installed October 10th 2022, and the sleeve on the 11th.
The 10th, first shutdown occured, at 18:59:24 .
Note : 6.0.0-1-librem5 was booted first the 10th at 17:15:30.
Between the 4th and the 10th, no shutdown.

Captain_Morgan · November 22, 2022, 3:40pm

can you roll back to the previous kernel?

frediz · November 22, 2022, 4:07pm

Hi @Captain_Morgan,
I guess it’s the only way to verify things. I was hesitant because I didn’t want to loose any potential
improvement in kernel 6, but my L5 shutting down unexpectedly is just a pain in the neck.
So thanks to your message, I’m back on 5.18.0-1-librem5 now.
Let’s see how it behaves.
In the meantime, I saw there is a thermal.nocrt kernel option that I understand would turn the
shutting down behavior off. But that will come in a second time maybe (disabling that safety needs to be
thought twice… )

I’m just wondering if my device is faulty in some way or if it’s the kernel . But in that latter case, I don’t
understand why I seem to be the only one experiencing this issue.

irvinewade · November 22, 2022, 10:10pm

Really you just need to stay on 5.x for a while and observe the behaviour and then form a tentative conclusion.

purismforum · November 22, 2022, 10:13pm

Personally I would never do that unless I am ok with the cpu melting on itself.

frediz · November 23, 2022, 9:08am

Right, let’s see. So far so good.

frediz · November 23, 2022, 9:19am

At the time CPUs didn’t have much protection, the machine started behave badly and just crash/stop.
I think cpu based machines still behave the same, let me know if I’m wrong. It’s not a nuclear power plant I guess.
That being said, repeated overheating is never good for the hardware for sure.
Also, I was more worried last time I’ve been watching videos on youtube on firefox with the phone being
really hot compared to the few times my L5 shut down because of those overheating protection
shutdowns.
I would just replace those kernel triggers with some software/script that would do the job in place in
order to understand and have more control.

Hey there,
as of today, almost a week later, not a single shutdown due to kernel overheating triggers with kernel 5.18.0-1-librem5 …
But I now have other issues : like microphone set to headset systematically after boot. So I have to change to handset every morning after turning L5 on.
Sometimes after I have switched to handset
following the boot and after receiving a first call, it would still be set to
handset, but if I get called again, people can not hear me. And I have
to reboot to again set mic to handset.
Not sure if it is related to some recent changes to call audio.
Also, systematically if I’m in a call and get a second call during that,
whether I accept it or not, the phone continues to ring/vibrate forever.
The 2 calls are “lost” and I have to reboot to stop the phone to ring/vibrate.
So now, I think I will go back to kernel 6 and see if shutdowns are still
triggered (and if I have the above mic/call behaviors which I don’t remember having had with 6.0).

F.

Captain_Morgan · December 1, 2022, 7:47pm

The continuous ringing also sometimes happens after picking up a call for me and while talking to that person the incoming call is from that same person. There are still a few items that need to be sorted out even with the new kernel.

frediz · December 1, 2022, 8:05pm

Shutdowns are back since I re-installed kernel 6.0 … at least first one this morning.
Later today I wrote a .service that would be triggered at shutdown time to dump temperatures.
This evening, I found my L5 off again… happy to see that. For once.
I looked at the logs :

déc. 01 18:48:10 pureos kernel: thermal thermal_zone0: cpu-thermal: critical temperature reached, shutting down
déc. 01 18:48:10 pureos kernel: reboot: HARDWARE PROTECTION shutdown (Temperature too high)

So 3s after the kernel overheat protection got triggered, my temperature hook showed (Temp thermal_zone...) : 23°C for thermal_zone[0,1,2] .
I don’t think my L5 could go from 95°C down to 23°C in 3s.

The sensors reading in /sys/… show 23°C which seems accurate according to the room temperature below that.
What’s going on, on my Librem5 ??
A kernel bug in 6.0 happening particularly well on my specific device ?

Could this be something similar to this .
Do we have something similar at 95°C on the hardware side on the Librem 5 ? :

Until then you can add thermal.crt=-1 to your kernel commandline to avoid the critical shutdown happening. There as not any danger this will damage your SOC as it has an internal safety shutoff at 105C

Thank you people for reading

Yep, pretty crazy behaviors . Sometimes people laugh quite a bit around me
