Raspberry pi 3b hangs with Libreelec 11.0.4 and Wireguard

    Dear all,
    I have a "portable libreelec" that I bring everywhere with me and I use to play, using wireguard, movies in my NAS.
    Since the last update to 11.0.2 I have noted that when I play a second movie from my NAS, I get this kernel error. Visually Kodi starts playing (the second movie) but video does not show and, after a while, the system become not responsive.

    Any idea? Perhaps I am doing something that I should not be doing with NFS over wireguard? Maybe of interest my autostart.sh file:

    Code
    (
  sleep 20
  ip route add 192.168.x.xxx via 192.168.y.1 dev wg0
)&

    This is the Kodi log:

    And this is the Kernel log:

    I am doing that right now. Re the log, unfortunately that is not a snippet, but the complete log. I will try to increase the log verbosity and provided it with PasteBin. Thanks

    The log file is short, because log level is 0. Set it to 1 or 2 by creating an advancedsettings.xml file. Log is only needed, if LE 11.0.4 doesn't fix it.

    PS:

    Code

    I haven't seen log level -1 before. That's not legit. ^^

    Thx. I don't think it's related to the kernel error from post #1. Looks like a network error to me:

    Code

    To rule out network errors, play the same movies directly from USB (thumb drive).

    Thanks for your support. After playing something from NFS, I played another video from SD to make sure it is not a network issue. Here is the pastebin obtained from pastekodi:

    Since I have started the new movie, kodi is not responding (systemctl restart kodi does not do anything) and this is the repeating output:

    I did some further experimentation:

    • I moved to mariadb
    • I hard-coded the nfs mount using the .mount service. I added the dependence in the service to the wireguard service, everything gets mounted as needed.

    result does not change. I still cannot play two videos one after the other and the error is the same that I posted last time :(

    I can play two "local videos" without problems

    Code

Feb 16 19:10:58.572201 MobileKodi systemd[1]: systemd-timesyncd.service was skipped because of an unmet condition check (ConditionPathExists=/dev/.kernel_ipconfig).

    Add a couple of seconds at "wait for network" (LE network settings).

    Went from 10 secs to 30 secs, still the same error when playing the second movie (and same kernel oops)

    What I found weird is that kodi is trying to reload some settings:

    To figure out the specific change that altered behaviour you need to "git bisect" the changes in our GitHub repo between 11.0.2 and 11.0.4 or narrow the time range to a specific day using bisect-like testing of nightlies between the release dates. I have hunch the NFS session needed for the persistent system mount is disrupted/lost after initial boot and playback resulting in Kodi losing "local" access to media. To understand/prove that you'd need to capture/analyse PCAP files, but they will be large (I'm not volunteering).

    Some thoughts: If you accessed media using the Kodi NFS client this expects connect/disconnect events to happen (whereas local media access does not) so that might prove more reliable than a system mount. I've also personally found SMB to be more reliable than NFS at accessing content remotely on my own hotel/remote device. These days I only use the native SMB client. That said, I also see too many issues with poor speeds in hotel networks so while I can access media over SMB from the NAS via a WireGuard tunnel to home; I mostly use the Plex add-on for Kodi to stream content from a Plex server running on the NAS. This only requires me to expose ports for Plex (so no WireGuard needed) and Plex can transcode content into a lower resolution (less bandwidth required) on-the-fly if the connection isn't running fast enough or I want to override/force the resolution.

    NB: I'd also put "ip route add" commands into a systemd service so it can be scheduled more accurately than "sleep 20" after the WireGuard tunnel is established. I doubt that's involved in the problem you're seeing though.

    Hi, this seems to be the exact same behavior we are discussing here:

    [RPi5] Kernel Panic After Selecting Live-TV Channel

    Hello,

    I recently bought a new RPI5 and installed it with:

    LibreELEC (community): nightly-20240116-0f6c393 (RPi5.aarch64)

    (i also tried it with 11.0.5 stable version but the result was the same)



    If i select a tv channel from the EPG i have a 50/50% chance that it completely crashes the system.

    (Code, 50 lines)



    From the kodi log itself it only shows these type of messages:

    (Code, 40 lines)

    Let me know if there is…

    So it seems to happen on:

    • RPI3b
    • RPI4
    • RPI5

    According to @Ozymandyaz the user in the github issue, it is not happening on 11.0.3


    Hope this helps to narrow down the search a little bit :)
