Regression: system doesn't start if no DVD drive is connected about wii-linux-ngx HOT 2 OPEN

@RattletraPM it is a kernel bug and it was already there in DeltaResero's version.

Thanks for clarifying out the exact way it affects the system.

I am not sure how this could be fixed though? It requires some kernel patch?

I've done a few more tests since making this issue and found a dirty fix.

The issue is indeed caused by the rvl-di driver, however trying to blacklist it simply wouldn't work. I tried both adding it to /etc/modprobe.d/blacklist and via the kernel parameter module_blacklist=, yet it would still get loaded and hang the system at boot.

Being the lazy person I am, I didn't want to mess with the source code and recompile the whole kernel, but before giving up I had an idea. What I thought about doing was to open the kernel's zImage in a hexeditor, find the device tree, find the string hollywood-di (offset 0x1B191) and change it to something else so it wouldn't be found at boot, and thus it would get ignored. I told you it was a dirty fix but hey, it worked!

So, I don't know how helpful this would be to make a proper fix, unlike mine, but at least there is a way to make Linux boot without a DVD drive for now. Most likely, giving an option to boot without DVD support via Gumboot would be enough if you don't want to touch the driver's source, so considering I know this is a niche issue, I'd say it could be an okay fix.
