Doesn't change the fact that it is not really helpful when it comes to logging
all errors properly.

  [ Properly means using a structured log format with the tracepoint and not
    dumping it into dmesg. ]

And figuring out what hw is failing so that it can be replaced. No one has
come with a real need for making it better, more useful.

You're coming with what I think is such a need and I'm trying to explain to
you what needs to be done. But you want to feed your AI with dmesg and solve
it this way.

If you wanna do it right, we can talk. Otherwise, have fun.
