I have been experiencing RPi4 Restarts at random. Attached are the /var/log/syslog for a boot following the crash.
I would appreciate any guidance you can offer on how to track down the source of the restarts
abritishthing
whats your power supply rating
abritishthing
sometimes there isnt enough power for the pi and it can cause issues unknowingly
abritishthing
another cause is that your sd card might not be fast enough

We have about 65 units deployed on a Custom PCB. I believe the chip's output is 5V1 @ 3A but I will double check. We are only seeing this issue at 1 of 3 locations.
No clusters. These are 1 PCB + 1 Pi mounted to Go-Karts.
abritishthing
oh darn
combatkevin
I appreciate the thoughts. Ruling out is still helpful!
abritishthing
could be a minor case of corupption?
abritishthing
maybe the write was successful but corrupted a tiny bit
combatkevin
There is a string of random characters printed either before the power cycle or after. idk if that's useful info but it's data.
abritishthing
just relised your using dietpi
abritishthing
try reflashing
abritishthing
it seems like the image may have gotten a tiny bit corrupted
abritishthing
so redownload it too
combatkevin
I was going to start with that and realized the plethora of changes required to do it. I think that's a great idea and will be proceeding with a fresh install. I am not convinced that is the source of the issue but...¯\_(⊙︿⊙)_/¯ Ya never know.
abritishthing
yeah
abritishthing
ive never really delt with huge amounts of pi's
abritishthing
you said they were mounted in go-karts
combatkevin
Regretting it over here. While they are nice, they're definitely prototypal devices at best.
abritishthing
yeah
combatkevin
Yea, electric go-karts 🙂
abritishthing
thats rules out power
abritishthing
and since storage is ruled out
abritishthing
it also cant be heat since the rpi to throttle its speed to stay in temp
combatkevin
We were seeing the karts drain too low and causing our boards to power cycle. I am wondering if that had the potential to fry a pi?
abritishthing
no
abritishthing
and what you just said means that the sd cards might be corrupting
combatkevin
Whereby that SD card should not be reused? A fresh SD installed?
abritishthing
fresh install
combatkevin
So the SD itself should be fine?
abritishthing
yes
combatkevin
Brilliant!
abritishthing
its just the data on the sd card is corrupting a lil bit each spike when the go-carts go
combatkevin
What could be corrupted that causes it to run fine except power cycle every once in a while?
abritishthing
ye
combatkevin
We did also get a "RPi Logo" Screen the other day on one of the karts. Power cycling resolved the issue.
abritishthing
that sometimes happens
abritishthing
i did it once
combatkevin
Do you know the cause? Surely corruption would keep it from successfully power on?
abritishthing
it happens if you power cycle too quick
abritishthing
its fine though
combatkevin
What is your experience with the Raspberry Pi?
abritishthing
stable, reliable
abritishthing
and pretty smooth
combatkevin
What I mean is what work do you do with them?
abritishthing
yes
combatkevin
How do you utilize them
abritishthing
just 1 though
abritishthing
for home use
combatkevin
I see. What is your profession?
abritishthing
just a programmer
combatkevin
What languages?
abritishthing
um
abritishthing
javascript
combatkevin
As for this issue, I will consider it answered. I appreciate your time! I will work on the new image and flashing an existing one on 2 of the karts giving us issues right now. See if one or the other resolves it.
