Unfortunately, changing the cable didn’t help.
I had to change k20 to k19 due to the incompatibility of one of the plugins I use. I checked on the last nightly k19: CoreELEC (official): 19.5-Matrix_nightly_20221118 (Amlogic-ng.arm), on 2 different USB ports.

I can’t replace/check more things - and without lights it’s not the same…
@Portisch
Any chance of a solution?
I’ll check on the second arduino board.
@ tomasiek You are using the screecapture (amilogic) feature of Hyperion, correct?
Please confirm.
The dumps point into that direction that the capturing a screen frame does not work.
It is not a Hyperion problem, but it uncovers the problem area, as Hyperion asks for a frame.
Similarly, it has nothing to do with USB…
Yes:
BTW - I also ruled out a problem with the box - it happens on two different devices
I had no time to check this issue. I tried to make it more save but it still had a oops. To be honest I wasn’t working for the last 6 months anymore on 4.9 kernel and it’s not so comfortable working on it like on 5.4. I will require more time
Of course. Each of us has his own life. So I’m waiting, but I hope that the problem has finally been identified.
bTW what if I manually uploaded only the kernel.img from the time when there was no error? i.e. before December 2021? Leaving the rest of the files as they are.
I went back to 19.3Matrix on Oct 25, 2021 - that was probably the last time it was ok… testing.
Nevermind - the same crash - i’ll try to use usb graber instead of amlogic
Please use this image:
Maybe use another boot media as it’s a debug build. When the kenel oops happen again please post the log, thx.
Crash with this image
http://ix.io/4gUN
http://ix.io/4gU2
And another (after ~1,5h)

http://ix.io/4ggE
(USB graber - it does not support HDMI-CEC, which excludes it from use)
I was now able to create a debug image of the kernel and it point me to this line:
Will need to take a look what happen here. Maybe the callback
get invalid while enter here, not sure.
Please make a log of the kernel oops again with this image, just to be sure I am looking on the correct line:
Ok - I’ll check it right now - we’re just starting to watch
Please test with this image again and post a new log on crash:
Ok - last test take about 3h…
Ok, next test image:
Approx. I think this will be my last test today - matches finished
The lights have been working for a few hours - so far without a problem, but it doesn’t mean anything yet because it happened that it worked for a few days and it was ok.
I think I covered the issue, but it should happen. I will make another debug image to find the reason.
But I will need more time to look what be the best solution for it. So continue testing with last image please.
After a few hours you can run on SHH:
dmesg | grep ++++
and see if you get some output. If yes the error happen but the system did not crash.
I’ve been watching something since 8:00 in the morning. It didn’t hang up. Yes, while watching one game he hung up (but it happens on this site). Hyperion is still running.

I’ll keep testing and will post another log tonight. Well done - I had no more ideas what could be the cause.
Thank you for everything - you put a lot of work into this. But as you can see with the effect.
Still works… You are great.
