[comp.sys.sun] need interpretation of panic message?

dove@uunet.uu.net (Webster Dove) (11/04/89)

We have begun getting kernel bus errors at no consistant address.  Can
someone help us by interpreting the following?

I see a large number of postings in various vendor-specific groups and
unix-wizards asking substantially the same question:

	What is a panic <keyword>?
	What does this traceback point at?

What I don't see is anyone posting or publishing a general answer, either
as a table of panics or as a technique using the kernel name- space maps.

I look panics up in the Lyons book, circa v6!.  (I generally ignore
mysterious tracebacks as my preferred/only technique is to use adb on the
core file, and I get tracebacks **only** when I'm not saving core
files...).

Would Sun or a consortium of wizards consider publishing a collection of
folklore about panics?  Or shall we just start archiving the answers as
they go by (:-)).
