Looks like we got a fix for the kodi lockup / kernel oops issue [le92] ffmpeg: update RPi HEVC patch to latest version by HiassofT · Pull Request #4411 · LibreELEC/LibreELEC.tv · GitHub , quick test on RPi3B+ with latest firmware went fine.
The fix will be included in the next LE release, for now please use the firmware revert workaround.

bleep42 I did some more testing and the issue seems to be firmware (not kernel) related.
Could you test LE 9.2.3 again and replace the firmware files in /flash with the contents from this ZIP? rpi-firmware-9e3c23c.zip
This reverts the RPi firmware to the April 15 version, with that your sample files played fine on RPi3.
so long,
Hias
Thanks for testing!
I could reproduce the issue with your samples on RPi3, it seems to be a kernel bug. I've pinged popcornmix and pointed him to this thread.

bleep42 did you overclock your Slice? If yes it might be worth testing with all overclock settings removed from config.txt.
There were changes to the RPi firmware regarding clock/voltage handling so overvoltage/overclock settings in config.txt may need to be adjusted.

Sd card in an usb reader will that faster boot up LE instead of sd card in the sd slot?
Probably not, because USB enumeration will take a bit. I haven't done any speed / time tests, just checked if my USB2 SD card reader (which probably isn't too fast anyways) worked.

Fresh install works fine..but if I update from 9.2.1 it doesn't start...
Thanks for the info - nothing unusual in the logs, except you voided warranty due to overclocking 
Have you tried updating 9.2.1 with stock config.txt? There were quite a lot overclocking/overcurrent settings in there...
It would be good to rule out any issues that could be caused by overclock, marginal power supply or dying SD cards (which still are the most common issues with RPi).
Also some more testing with your stock 9.2.3 installation would be interesting.

Mario77 it's very puzzling that a fresh install of 9.2.3 worked but then failed after restoring the backup.
Could you try installing 9.2.3 fresh again and then ssh in and post the output of
journalctl -a | pastebinit
cat /proc/cpuinfo | pastebinitAlso try using 9.2.3 with stock configuration for a bit (eg play local media, reboot) and see how that works.
Testing with another SD card may also be worth a try, maybe the one you were using is starting to fail (that would explain why boot failed after restoring backup).

Does this release include the latest firmware required for USB boot?
LE 9.2.3 ships with the May 27 RPi firmware which has initial support for USB boot.
Note however that RPi4 USB boot is in early beta testing stage and you also need the beta bootloader EEPROM update which is not included in LE.
So while it may be possible to boot LE 9.2.3 from USB (it worked for me with the LE SD card in a USB cardreader) it's not something we support ATM or even encourage you to try.
If you run into issues it's best to test with the Raspberry Pi OS (former Raspbian) instead of LibreELEC - chances are high that there are issues with several USB devices/adapters. Check the instructions in the USB boot thread on the RPi forum USB-MSD boot EEPROM update - 2020-05-28 - Raspberry Pi Forums and report issues there.

Updated Rpi2 with 9.2.3 now just got a black screen...no libreelec welcome screen..no ssh..
Did you overclock your RPi? If yes, please try removing any overclock settings from config.txt.
I just tested a fresh LE 9.2.3 installation on RPi2 and it worked fine.

Hias
Dont do that, you are bricking your LibreELEC installation.
Only replace start.elf and fixup.dat, eg with the script or instructions in the linked post, and make sure no other start/fixup files are present.
It may work for you now but if you have other start/fixup files on your SD card your RPi won't be using the one needed for LibreELEC and on later LibreELEC updates you'll still be using that old version which can cause a lot of headache for you.
USB boot is working fine here with the May 27 firmware and bootloader versions.
so long,
Hias
Be very careful, don't touch any dtb files and make sure you only change start.elf and fixup.dat (which are start4x.elf and fixup4x.dat in the RPi firmware repo). Otherwise chances are high you'll brick your LibreELEC installation.
Read more about it here: Pi4 USB Boot is coming soon!!!! YAAAY

Please wait with testing, we just noticed a bug (probably in the RPi firmware) that causes issue and prevents kodi to start on RPi0/1 - quite certainly Slice is affected, too.
I'm terribly sorry about that, seems I missed it in final testing 
so long,
Hias
Yes, 9.2.3 will contain the fixed firmware and the manual steps I posted are no longer needed.
The changes aren't in our repo yet, we are currently working on it.
so long,
Hias
Please post the full output you get in putty, not only the commands you typed/copied in. wget will show some info/status and that's important.
And, again, no, vcgencmd bootloader_version is not the correct command to check the version of the firmware. vcgencmd version is the right command.
I already posted all of this in detail here Noise / artefacts when playing back 4K HEVC video on RPi4 + LE 9.2.1 (no problems on LE 9.2.0)
TBH if you can't follow these steps and don't understand the difference between bootloader, RPi firmware and VL805 firmware I think it's better you stay away from beta-testing and wait until the final version is released.
so long,
Hias
When I do the steps in LE with putty and after all reboot and check
Codevcgencmd bootloader_versionI see still the april 16 2020
Which steps exactly did you do and what was the console output?
The script I posted in this thread and the instructions I posted in the artefact thread are for updating the RPi/VideoCode firmware. It won't affect the bootloader.
so long,
Hias
No, the steps I posted are specific for LibreELEC, they won't work on Raspbian (they'll just mess up the firmware files for RPi0-3 there).
If you have issues with Raspbian please post in the thread on the RPi forum.
so long,
Hias
The instructions I posted are for updating the RPi/VideoCore firmware on the SD card / USB device. On Raspbian "rpi-update" takes care of that step. Without that updated firmware the bootloader will refuse to boot from USB media.
The bootloader eeprom on the RPi has to be updated separately to the beta version. This is done via "rpi-eeprom-update". While LibreELEC contains the rpi-eeprom-update/rpi-eeprom-config tools it doesn't include the beta bootloader - you'd need to manually download that from GitHub - raspberrypi/rpi-eeprom: Installation scripts and binaries for the closed sourced Raspberry Pi 4 EEPROMs . Or boot Raspbian on the RPi and follow the official instructions Raspberry Pi 4 USB mass storage beta (beta means it not ready yet, and not officially released!) - Raspberry Pi Forums
The same warning as in the RPi thread applies to LE, too - even more so as LE is a bit different than Raspbian.

Please read again through what I posted in this thread,I already told you what our plans for the LibreELEC 9.2.3 release are.
