The comp freezes completely after accessing it in any way ( I don't even get to mount it...). The Kernel dumpes a core saying the swapper is unable to sync disks and the computer freezes. I can't copy the dump from the screen and I can't find a .core file.

When the kernel panics, you don't get a core file. What you do get instead is a dump to console of the stack state during the crash. This is pretty much useless unless you are willing to do some kernel debugging.

If you are willing to do it, you will need to get panic's output. Unfortunetly, at that stage, you don't have a kernel to copy/paste or write to disk with. Worst yet, the text usually scrolls off screen, and you can't even see all of it or scroll back. At work I solved this problem by hooking up my Linux machine to my Windows machine using a serial NULL modem cable, and directing the console to /dev/ttyS0. This dumps the stack upon panic to the serial, and a terminal program sits waiting there to receive it. You can then procede to post-mortem it.

Better ways are the sys-req key and the kernel debugger, but I am, unfortunetly, not familiar with how to work them.
