[RPI4] Pressing certain remote buttons using CEC can cause system reboots LE 12.xx

Hi,

I recently upgraded two RPI4s to LE 12.01 from 11.06. Both are connected to TVs.

The one connected to my Samsung TV will crash/reboot if I press certain TV only buttons on the remote. I have a "Menu" button used for adjusting TV display settings like brightness that has always been completely (correctly) ignored by Kodi/LibreELEC. Pressing that button can cause sytem reboots. Not always, but intermittently. The crash log appears to show the CEC code as the culprit.

I noticed the double CEC adapter present in 12.01 and then this thread [RPi4] Multiple CEC Adapters with LE 12.0.1 , so decided to try the latest nightly build: LibreELEC nightly-20250116-37e4458. This build fixes the double CEC adapter entry but I am still getting intermittent system crashes when pressing my "Menu" remote button.

Reverting back to LibreELEC 11.06 returns rock solid remote/CEC stability when pressing "Menu".

Thanks.

I'm still in forum jail I guess so I can't edit, but I should have included a link to the crash log in my post above. I take it you don't like them being pasted into the post itself.

Enable debug logging, then enable CEC in component specific logging. Reboot, cause the crash and post a new log.

That was a LE 13 nightly: LibreELEC nightly-20250119-c72d843. I didn't expect it to be fixed automagically, but figured I'd give a LE 13 build a try.

Thanks.

I should also add that the "Source" button on my remote has also caused the crash/reboot issue. It only happened a couple of times, but I don't use that button as nearly as often as "Menu".

I have replicated this bug on the Raspberry Pi OS with Kodi 21 installed. I got dumped back to the RPi OS desktop out of Kodi on a "Menu" button press.

Still rock solid in LibreELEC 11.06 with Kodi 20.3.

So, I guess that means this bug is either a Kodi 21 CEC code bug or a Linux CEC library bug.

Are the devs here in contact with the Kodi team?

Thanks.

Ha, I just realized popcornmix is Kodi dev after looking on the Kodi forum. Guess that anwers my question.

Shame I can't edit my own posts yet. Still in forum jail.
