What does fail to initialize ptp_kvm mean? What is wrong?
Nothing, it just means that this kernel version is missing that patch, feel free to ignore as recommended here. The ptp_kvm features are used for VM time sync, definitely not your concern here

It is a brand new cable.
that's not the point - did you try some of these troubleshooting actions from the url which I provided? eventually you may gather more insights of your problem following these attempts...

What should I do next?
This seems to be a popular problem, see for example here. It looks like you need better hdmi cable.

This also did not work for me.
dmesg | paste - this shouldn't be too big, so as far as your RPi has network access it should work
for large kodi.log you can split it for chunks smaller than 512 kB:
Bash$ cd /storage/.kodi/temp/ $ split -C 500k kodi.log ksplit_ $ find . -name "ksplit_*" | xargs paste -i -
unfortunately it simply returns with the prompt.
It happens usually when log file is huge, pastebin has limit of 512 kB

I cannot provide something that did not exist (repeating myself). The RPi4 crashed multiple times, and by crash I mean that it was inoperable to the point that it required me to reinstall LE over and over again.
one option is to take out the disc (or microSD) from just crashed RPi4 abd mount it in another Ubuntu machine, then restore logs - see here for some ideas
-
don't use any scrap parts
Well, I used official RPi 3A power supply and without addidtional PSU my 500 GB ADATA SSD worked only on USB2 socket, while it was not recognized on USB3 sockets, so after all I'm good, but perhaps I had just some luck here.
RPi5 seems to have more power juice on USB sockets, this is might be another reason to wait for it.
-
The SSD drive does not have its own PSU.
You may also check if connecting via USB2 changes anything - I found out surprisingly that USB2 sockets on RPi4 provide more power than USB3 sockets.
-
That doesn't really seem to be helpful to me.
really? there are few more suggestions on this thread than just new hdmi cable
for example hotplug trick.besides there is also guidance there how to create and post full debug log, which seems to be your next option here

I installed LibreELEC-RPi4.arm-11.0.3.img.gz using the LE installer on my MicroSD 128GB but my system is just telling me there is "No Signal on my HDMI 2 port".
Probably dead microSD - check your LED flash codes as described here.
-
The power button works pretty much as on a PC: if you press it for a shot time it'll do a graceful shutdown and if it hold it for 5s it'll do a hard poweroff (needed when the system/kernel completely locked up).
They claim that RTC that can wake up your Pi from sleep mode and it’s programmable - I wonder if that also means that remote can wake it up easily with some setup...
-
However this plays nicely with LE12-nightly, so I suppose this is the way

The movie starts without video, just with the sound. I see this in the log:

So here is my small pet-project to create handy HTPC device for vacation travels. There are multiple sources how to setup new remote type (here and here) and how to connect TSOP receiver (here), unfortunatelly all a little bit outdated.
So I noted all my steps into this short guide.
Hardware:
- RPi4 4GB
- Argon Remote (why this one? I had a spare, and besides I like its terse design)
- TSOP sensor (any type for 38 kHz will work, I used TSOP4838)
Software:
- Installed latest stable LE11 on RPi4
- TSOP in my case was connected to GPIO pin 23, so following line needs to be added to config.txt (you can edit it directly on the SD card):
dtoverlay=gpio-ir,gpio_pin=23
- Connect via SSH to RPi4 and create with nano editor these 2 files (see for the contents in the attached zip file):
/storage/.config/rc_keymaps/argon40.toml
/storage/.config/rc_maps.cfg
That's it, pretty simple. Attached few pictures from my setup, I used alu fanless cooling case and drilled hole in it to expose the sensor.
Enjoy!

I know, I can't wait for biodegradable processors either, but for now I consider 2-3 years old electronics as a crap, no matter how much it costed initially. That's why I replace my smartphone after 2-3 years too. Yes, what a waste, coming generations would need to fix it.
Shutting up now, this is completely off topic.

Super cheap also means super cheap software, and no chance to install other OS's. Something under 50$ should be OK.
Right, you can find some Android boxes which can run 8K video on pre-installed Kodi for around $40 (if you filter out all the really cheap crap), and they are ready to go (with remote, power supply etc).
But still you may find hardware issues after a year, or updating to latest Kodi will be impossible etc.
On the other hand with RPi4 you need:
- RPi4 2GB RAM = $35
- IR Remote = $15
- MicroSD 1GB = $2
- Power Supply 15W = $12
- Micro HDMI to HDMI Adapter = $9
- Alu case = $12
So in total around $85.
Buying some $40 android player and put it in the trash after 2 years when it breaks and buy again another one for $40 might not be bad strategy after all
