Fatal server error:

Also, at boot up, the first thing I get onscreen after grub inits is:
[ 0.598030] pci_root PNP0A08:00: address space collision: host bridge window [mem 0x000cc000-0x000cffff] conflicts with Video ROM [mem 0x000cc000-0x000cedff]

I don't have PAE/NX enabled? I thought I had the stack protection things running?

(I wish I installed the 64bit version of debian but, I didn't , ohwell. I heard that NX bit or page based stack protection etc doesn't work in x64 mode )

How do I do the strace, and should I PM you the log of it? I use an encrypted SSD btw, will it contain my crypto key, I don't want that to get out.

Maybe you can try temporarily deleting the special kernel you must use for security, and remove the radeon card that appears to be causing so many problems, and for security, since the data on your computer is apparently so sensitive, you should remove the hard drive as well. Then, because data in the RAM may be read by the Government Agents who routinely patrol your neighborhood with jugs of liquid nitrogen, you should remove that as well...just to be safe, you know. Now, to be REALLY REALLY sure no one can nick your data, you can use the secret NSA technique I use: Remove the cpu from the motherboard, turn it over and VERY carefully, with a small pair of wire cutters, clip off every 5th pin on the underside, then reinstall it. Now boot the computer and post the results of dmesg.....

Edit: Crap! I almost forgot the most important thing for keeping your data secure; I almost forgot the Government mind Reader Satellite for Emaciated Crackpots..(grsec) Protocol. Be absolutely sure you don your tinfoil hat before booting your now-safe computer.

2nd edit: It would appear that the time-honored method of defeating the grsec protocol with a tinfoil hat is no longer effective. The Government has learned how to use the 8th Barsoomian Ray of Repulsion to create a subatomic singularity that can penetrate tin foil. The only way to keep your data safe now is to pull the power cord out of a lamp, separate the 2 wires, bare 6" of the end of each wire, wrap the two bare ends securely around each ear, and plug it in to the outlet. This will scramble your brainwaves so they cannot tell what you are thinking.
