If it's considered harmful, better remove all references to ksymoops.
2.4 users will happily grab their copy of this file from 2.4 tree.

I opted to keep the entry but make an explicit note that ksymoops should not
be used for 2.6 kernels to make it clear. There are still people who use
ksymoops on 2.6 Oops messages, so I thought it would make sense to keep the
entry but make it clear that you should /not/ do that.
But, I'm fine with removing it as well.

Here's a patch to remove the Ksymoops entry instead.
I'll leave it up to the powers that be to sprinkle holy penguin pee on the
preferred version.
Ksymoops should not be used on 2.6 Oops messages, so remove the ksymoops entry

You'll probably want to upgrade.

OK, but what should I use then with 2.6??
And since when is ksymoops not usable with it?
I have reported quite a few times here, alaways with 2.6.x and nobody said anything about it...

You should just enable CONFIG_KALLSYMS so that the kernel can
report (decode) the symbols with the oops message.
Yes, ksymoops will still work, but it should only be used if
the kernel was not configured with CONFIG_KALLSYMS, and some
people say that the kernel oops + symbols are better than
the ksymoops output. I haven't compared them so can't say.

Nothing at all.
Just post the raw Oops message as-is (from console or dmesg).
> And since when is ksymoops not usable with it?
At least since 2003 and the 2.5 kernel series.
The oldest reference I could find in the archives is an email by Dave
Jones dating back to Mon Apr 14 2003 - 14:31:44 EST
http://www.uwsg.iu.edu/hypermail/linux/kernel/0304.1/1533.html
The interresting part of that mail is this bit
"Merging of kksymoops means that the kernel will now spit out
automatically decoded oopses (no more feeding them to ksymoops).
For this reason, you should always enable the option in the
kernel hacking menu labelled "Load all symbols for debugging/kksymoops".
"

They should have.
Please read a recent Documentation/oops-tracing.txt (here's a link:
http://sosdg.org/~coywolf/lxr/source/Documentation/oops-tracing.txt?v=2.6.14-rc2
)
See the note at the top :
"NOTE: ksymoops is useless on 2.6. Please use the Oops in its original format
(from dmesg, etc). Ignore any references in this or other docs to "decoding
the Oops" or "running it through ksymoops". If you post an Oops fron 2.6 that
has been run through ksymoops, people will just tell you to repost it.

Raw Oops output. From logs, serial console, monitor photoed with
digital camera, copied to paper with pencil...
