[3.] Keywords (i.e., modules, networking, kernel);

I don't what you are asking here, excuse me ...

[4.] kernel version

I use kernel 2.4.3

[5.] Output of Oops.. message (if applicable) with symbolic information
        resolved ...

I think this information is in the point 2, I copies it manually, I hope it
hasn't errors, I was very carefully.

[6.] A small shell script or example program which triggers the problem (if possible)

I think it is not possible because the bug succes when i tried entering linux ...

[7.] Environment

I don't undestand this point, but I use linux because I am a programmer, I use
specially gcc and now I begin use apache and PHP ... perhaps the reason the bug
kernel occurs after httpd is because I used apache and PHP ... I don't know ...
I use apache but my PC isn't a server that host a web pages. My PC don't use any
local area network, and I specially use by doing C programs ...
