I've seen a few of these, and they _all_ seem to be related to module
use. I simply cannot debug panic's that happen in a module (as you can
see, the stack trace and EIP are not even found by ksymoops), especially
as I don't even know _what_ module it is.

Note that it's possible to make insmod dump the symbol table to /tmp,
and so if you know that you need to debug a particular module, it is
possible to interpret the stack trace --- manually.

Perhaps Bjorn (hint, hint) could be pursuaded to think about some scheme
where insmod dumps the symbol table in some standard location, based on
the module name, and then update ksymoops to understand how to look at
those additional symbol tables? :-)

(Or someone else might pick up this task, but it seems to me that Bjorn
might be the most qualified to make the necessary changes to the modules
distribution. Yeah, yeah, right. I'm sure he appreciates the vote of
confidence. :-)
