Hi JunGyu,

According to the log attached, it seems like the "v4lvideo" related part cause kernel panic.
We check the related projects folder for Amlogic's patch (common ; vendor/amlogic/common/apps/LibTsPlayer ; hardware/amlogic/media_modules) and all the Amlogic's patches are exist.

BTW, There have some patches update today in vendor/amlogic/common/apps/LibTsPlayer from Amlogic

Thanks
Peter

Hi Peter,

I don't understand why this kernel panic occurs on EAGLE.
As you said, if all of Amlogic's patches exist, it's seems that this issue was caused by a modification from FXN.

Can you check if some modification in FXN is causing this issue?

PS. There have some patches update today in vendor/amlogic/common/apps/LibTsPlayer from Amlogic <<< This patch was released due to other issues.

Thank you.

Hi JunGyu,

I check that FXN doesn't have related modification and all the Amlogic's patch from e-mail for ATV12 are applied and exist.
Could you help to check is there any other patch from Amlogic not in the e-mail loop and need to be applied?

Thanks
Peter
