System hang (sometimes)

1st Official Post

    Sometimes my system just hangs. This happens every two weeks or so. Most of the time i'm not at home and my wife reboots the device which leads to loss of logs.

    Now I was home.

    dmesg:
    VeCi

    kodi.log:
    KJPD

    I think the dmesg displays the error, but I don't know for sure.

    I'm using a Intel NUC (D54250WYK)

    Some of your added repos are questionable 3rd party repositories. Addons from those repos can contain functionality beyone our control. A test with a clean setup (a bootable usb stick with LibreELEC, and no added repos) should clarify things.

    Which dmesg error are you referring to?

    The Call trace is not normal behavior i believe.

    What repro's are you talking about, I've removed all banned repro's I believe, all other repro's are legit and contain normal addons.

    what klojum wants to say is, that it would be best to have a clean kodi. That means no repos addons beside the officials should be installed.

    You are right, there seems not to be a banned repo installed, but also those other repos or addons might cause an issue probably. So you could rename your .kodi folder to something like "kodi-bak" and reboot. That's like a factory reset. All addons and settings are 'gone', but backuped in the "kodi-bak" folder. So it's easy to restore them after testing.

    If the issue is gone after renaming the .kodi folder, one of the repos/addons might be the issue. So install them one after another and see, after which addon causes Kodi to hang.

    If the issue still persists, please get us a new (clean) logfile.

    Okay, I see what you mean. The problem is, this happens only once in a while. It's not reproducable. I do have deleted some of the Repro's, which weren't in use anymore, but removing all of them would result in a discussion with the wife. I'll try and find out what she hates more. A few weeks without the addons, or the incidental power cycle.

    It's easily done if you rename the folder...

    ssh in and

    Code
    mv /storage/.kodi /storage/kodi-bak

    every setting and add-on is now stored in "kodi-bak". But Kodi won't recognize this folder anymore.

    reboot after the command above and Kodi will create automatically a new .kodi folder with all settings at default and no add-ons/repositories installed.

    Then test if the issue comes up.

    if it doesn't come up, install one add-on after the other, to see when (or if) the issue comes up then.

    if you want your add-ons and settings back for a moment...

    ssh in again and:

    Code
    rm /storage/.kodi


#don't reboot after that!!!!!!!!!!!


mv /storage/kodi-bak /storage/.kodi

    Note: the text after the "#" is just a note for you and not a command to enter.

    reboot after you did both commands and you should have your add-ons, repos and settings back.

    Greetings

    This is the reason for your hang:

    Looks like this is caused by DVDPlayerVideo, which is odd no matter what addons you have installed. I have had the same NUC model as you for a couple years and never had a kernel crash like this. Hard to say what's the root cause here, could be either HW or SW.

    Mmm.. thanks for your answer, could it be BIOS releated? I'm using BIOS 41 (latest) from Intel. Or maybe I should install from scratch, i'm using this install for a pretty long time, with constant upgrades and updates.
