I'll test out the downgrade to 73d8102298719863d54264f62521362487f84256 just to be sure, then see if I can take it further back. 73d8102298719863d54264f62521362487f84256 still breaks for me, so it's definitely not related to the conversion. Any hints on what I can do to figure out what

Any hints on what I can do to figure out what layer it's stalling at? I have no idea. I would do a git bisect to try and narrow it down. Problem with the bisect is that I can't be sure what version it actually worked on. It certainly predates when my patch for my card was committed.

And important for me, because if it IS related to the vb2 conversion then I need to know asap. Might take a few days to be completely sure. I've wondered if it's something to do with the signal too (maybe some bug when signal error occurs?). So many variables :( I can reasonably

That sounds plausible wrt timeframe, but if cx23885 only started using vb2 after Sept 8 then it couldn't have affected me before then right? You are right about that. You are using DVB right? Not analog video? (Just to be 100% certain). Yes. Australia mostly has no analog anymore.
