What is included in kernel mini dumps?

Is it documented anywhere what is exactly included in kernel mini dumps? I tried to get some info out of one and most of my commands that I use would either fail or return some nonsense.

Not much, which is why I tend to override that setting. You get registers, the stack of the current process, and parts of kernel memory.

Yep, I noticed it too. But sometimes the mini dump is all you've got. Thus, the latter, "parts of kernel memory" is what I'm interested in. Is it documented anywhere?
