the above is the source of your problem!
prune_dcache did a NULL pointer exception.
Please use a newer kernel like 2.6.12.1, then your problem should go
away.

If not, please post to the linux kernel mailing list:
linux-kernel@vger.kernel.org

Martin

I agree that it may be simple. But I never need it before, and in my
job, it  will be useless...


Then just don't use it.

Everyone say me this. Google is not the magic answer to all my
problems. I  first post because a kernel panic. The kernel log let me
think about a  problem with my server, and since I removed the plugin
I think it was, my  server is fine again. Maybe it's the plugin, maybe
the kernel, maybe other  thing...


Well, one problem is, that you still did not post the _full_ panic!



Instead of saying things I don't understand, search google, try to
help  people by showing them what to do, not what to search.

One day, I had to make some search about firewalls. I said my firewall
was  on windows, but works like linux. All the linux people I meet
about this  were laughing at me. After, one guy took me, and explained
me how it works,  and we have talked a lot... I finaly undertand what
is was about. Now, I can  write some line in my firewall script.

So why don't share your knowledge with noobs like me instead of saying
"go  ask google" ?


Because to explain all the stuff would take too much time. And I have to
work too much so I have no time to explain everything.
And all your questions are already answered in the WWW. So just search
for it and find the answers...


Why when we use linux we must absolutly know how to hack the kernel to
get  more fps ?

I use linux because it's stable, faster than windows for some
applications... But don't say me that it is easyer to tweak... One
example :  change monitor resolution, color depth, refresh rate in a
few clicks...


I did not say that. But und most Windowmanagers it's like windows's
colored clicks.



I stop here because I have to get back to work, and I don't want to
make a  discussion about that.


Thanks!



I will try to compile the kernel, but I think I may help the plugin
developper, by helping him to solve that bug...


You said you get a kernel panic, that is not allowed to happend for a
normal userspace program. So if the plugin author did not manage
something correctly, the server should just SEGV.

But a kernel panic... Bad memory, a Kernel bug, a 3rd party driver or
a root program that accesses the wrong parts of the kernel...


Regards,
Martin


ps.: since you are using Ubuntu, why don't you contact the Ubuntu kernel
guys? It's a kernel problem, not a hlds one (I guess because of the
panic)!

No, but it does pay to learn what the 'save' button does.

No, but before driving a car, you should learn how to drive.

And before fixing an engine, you should learn how the engine goes together.


This is non-sens... Why not just use linux ? Is it really important in my

Why not just use it? Perhaps because its not working for you?

Because you wouldnt have the need to waste your time here :)

 Kernel compilation is never useless. it's the first thing I learned how

 hacking the kernel, and compiling the kernel are two very different
things. upgrading your kernel is similar to upgrading any software
package, it has bugfixes, updates, and many other things that help your
system run more smoothly.

As for sharing our knowledge, 90% of us learned from using google or
similar search engines, there's a wealth of information available out
there, and it's far more complete than any of us could sit down and write
to you.  There are tons of forums available for you to ask questions in as
well, forums that cover a much broader range of topics than just HLDS_L.



I use linux because it's stable, faster than windows for some
applications... But don't say me that it is easyer to tweak... One

Linux is definately not easier to tweak, but I think it's definately more
fun :)

developper, by helping him to solve that bug...



 the developer will want to know a LOT of information about your kernel
version, what options are enabled, and what happens if you update in order
to track the bug down.

Hi

I don't know why, but since 2 days, my server gives me kernel panic.
When looking at the log, I see 'srcds_run exited with preempt_count 1'.

I'll make a filesystem check, a file backup, remove plugins, and wait for
