Ksymoops
--------
If the unthinkable happens and your kernel oopses, you'll need a 2.4
version of ksymoops to decode the report; see REPORTING-BUGS in the
root of the Linux source for more information.
If the unthinkable happens and your kernel oopses, you may need the
ksymoops tool to decode it, but in most cases you don't.
In the 2.6 kernel it is generally preferred to build the kernel with
CONFIG_KALLSYMS so that it produces readable dumps that can be used as-is
(this also produces better output than ksymoops).
If for some reason your kernel is not build with CONFIG_KALLSYMS and
you have no way to rebuild and reproduce the Oops with that option, then
you can still decode that Oops with ksymoops.

If you run into some kind of deadlock, you can try to dump a call trace
for each process using sysrq-t (see Documentation/sysrq.txt). ksymoops
will translate these dumps into kernel symbols too. This way it is
possible to figure where *exactly* some process in "D" state is stuck.
