Many problems since last upgrade

Since the upgrade to Kodi v19, the kodi.bin processes cannot be terminated anymore. Neither is systemd able to stop them, nor does kill with any signal succeed. Currently I have 21 kodi.bin processes running. Here is an example from the journal:

10:00:02 Stopping media center application...
10:00:23 mediacenter.service: State 'stop-sigterm' timed out. Killing.
10:00:23 mediacenter.service: Killing process 21697 (mediacenter) with signal SIGKILL.
10:00:23 mediacenter.service: Killing process 29676 (kodi.bin) with signal SIGKILL.
10:00:23 mediacenter.service: Killing process 5555 (kodi.bin) with signal SIGKILL.
10:00:23 mediacenter.service: Killing process 21712 (sudo) with signal SIGKILL.
10:00:23 mediacenter.service: Killing process 21713 (kodi.bin) with signal SIGKILL.
10:00:23 mediacenter.service: Main process exited, code=killed, status=9/KILL

10:00:23 Stopped media center application.
10:00:37 mediacenter.service: Found left-over process 29676 (kodi.bin) in control group while starting unit. Ignoring.
10:00:37 This usually indicates unclean termination of a previous run, or service implementation deficiencies.
10:00:37 mediacenter.service: Found left-over process 5555 (kodi.bin) in control group while starting unit. Ignoring.
10:00:37 This usually indicates unclean termination of a previous run, or service implementation deficiencies.
10:00:37 mediacenter.service: Found left-over process 21713 (kodi.bin) in control group while starting unit. Ignoring.

10:00:37 Started media center application.
10:00:37 Starting Kodi...

The newly started Kodi doesn’t start correctly because of the allocated resources.

I am running OSMC on 3 RasPis and have this problem on 2 of them. On the one making most of the problems I also see some exceptions in the kernel log:

Last but not least, the RasPi does not start without a monitor/TV connected, even if I set hdmi_force_hotplug=1. In the journal from this boot I find another nullptr exception:

Hi

It might be fixed in the next update.

To test this update:

  1. Login via the command line
  2. Edit the file /etc/apt/sources.list
  3. Add the following line: deb http://apt.osmc.tv buster-devel main
  4. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  5. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.

Thanks for the hint on the development channel. Might be related to Kernel OOPS after update to v19.

Hi @sam_nazarko,

Thank you for this tip! It works much better now: It starts without an HDMI device connected,

One new issue arose: The kernel throws a warning every 10s now:
