  • mmu page fault on Odroid C2

    Thanks for the reply,

    So the visualisation in Settings / Player / Music / Visualisation is set to None.

    The de facto visualization with the Youtube plugin is the Album cover art as displayed in YT Music phone app. But this is what triggers the artifacts and glitches.

    If I configure the Youtube addon to play media "Audio Only" then I only get a "Youtube" written as static visualisation instead of the album art as before and nothing nasty happens, all seems good.

    I guess I will try to use the image you provided to see if newer kernel and newer drivers improves things.

  • mmu page fault on Odroid C2

    Hi,

    I'm using latest LibreELEC 11.0.3 on my Odroid C2 and I have some issues. When playing music via the YouTube addon, my screen starts to show nasty artifacts and flickering. I see no errors in the Kodi log, however in dmesg I see this, every single time I start playing a song like this:

    [ 140.927199] lima d00c0000.gpu: mmu page fault at 0x44d01c0 from bus id 0 of type read on ppmmu0

    Here's the a full boot log:

    I really don't know where to start debugging this. I've spent some time reproducing this and looking into kodi log, but with or without debug info, I still don't see any errors there. So this mmu page fault error seems to indicate there is a kernel bug somewhere.

    Anyone care to help with this ? Maybe it's an obvious thing like "Oh we don't support Odroid C2 anymore since LibreELEC vX" or whatever, but at least something.
