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.
Ok thanks for looking into that. No rush as far as I'm concerned. Slice working very well as is.
