Here, it seems to me we get the hotplugs for AVR/TV power cycling just fine,
and the EDID reading succeeds when they are powered back on. AFAICT the EDID
failures happen when we get hot *un* plug for the power off, we still have the
cable connected, and fail to read EDID. It seems a bit ugly, sure, but from
kernel driver perspective I think it's functional.

What does xrandr --verbose say after you've power cycled the AVR?
