I am assuming "SVIDEO-1" stems from the line:

> [    0.645655] [drm:update_connector_routing] [CONNECTOR:38:SVIDEO-1] using [ENCODER:39:TV-39] on [CRTC:26:crtc-0]

I seem to have the same problem (stack trace is very similar) as I have
reported in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1689651.

But the workaround with disabling SVIDEO-1 doesn't work for me. So I was
wondering if there are anything else I should be looking for? Or can help out
with?

I am suspecting that the problem in effect renders Linux unusable on a whole
lot of laptops, particularly for mine, so if there is anything that I can do,
I'm happy to.
