More words would be useful.
it did the thing just before I went to bed, sorry, I just want to keep the stone rolling. I don't know in which time zone you are located, I'm in CET.
"failed" is mentioned eight times in Ubuntu Pastebin (I used in Ubuntu's service as I could not register at PasteBin) in addition to timeouts

Can you confirm that you installed Ubuntu on your pi that has problems with libreelec,
and it produces that error in dmesg?
I took the Pi out of the box and used LibreELEC USB-SD Creator, as that failed, I opened this thread, nothing else, no modification etc.
I took the SD Card with "Raspberry Pi OS using Raspberry Pi Imager" from my running Pi 4 8 GB. That booted and was usable.
Afterwards, I tried OSMC (OSMC Installer), which runs well.
I can try to boot it up with Ubuntu if you like.
Doing a swap test (with a different pi4) could also confirm this
I should be able to do this tomorrow (maybe tonight, childcare is on me tonight)
