[RFC PATCH v2 19/26] docs: reporting-bugs: decode failure messages [need help!]

[Thorsten Leemhuis <linux@leemhuis.info>]

This part is quite similar to the old text and just a placeholder for
now. It and the referenced document afaics need to be revisited, as they
seem outdated to me. But I'm not really familiar with the current state
of things in that area and thus didn't feel qualified to write down
anything better quickly.

So consider this a request for help for those that know this area. Could
you maybe write something that would fit in here? Or outline the current
situation roughly in a reply (when is scripts/decode_stacktrace.sh
enough?), as that will make it easier for me or others to write
something? It should answer questions like "when is this actually
needed", "what .config options to ideally set to make this step easy or
unnecessary (CONFIG_UNWINDER_ORC when available, otherwise
CONFIG_UNWINDER_FRAME_POINTER)?".

+Decode failure messages
+-----------------------
+
+    *If the failure includes a stack dump, like an Oops does, consider decoding
+    it to find the offending line of code.*
+
+When the kernel detects an error, it will print a stack dump that allows to
+identify the exact line of code where the issue happens. But that information
+sometimes needs to get decoded to be readable, which is explained in
+admin-guide/bug-hunting.rst.
