[SOLVED] gnome-totem causes kernel video error

I´m not sure if the underlying problem is caused by the kernel, raspberry video drivers, or the gnome-delivered totem player... playing a video works well until totem is closed or asked to load another video file on the fly... any ideas?

Re: [SOLVED] gnome-totem causes kernel video error

Possibly a codec issue, what was the video format you were trying to play or is all formats. But get a backtrace as mentioned.

Re: [SOLVED] gnome-totem causes kernel video error

Update... this error, which was independent from the codec used, is gone with the upgrade to kernel 5.10.110... the version which showed the error was 5.10.90.
