Tried the hardware check which didn't work, which the instruction page says is because I need the Mac OS X install disc 1...
...Unfortunately I don't have the original installation discs bought it from a classmate at uni and it was her brothers and he lost/threw them away with the box back when he bought it new... blah blah etc
Is there any other way I can do this check or find out what is causing the panic?
Forgot to add the spec before, so here it is:
Macbook 13" Unibody 2.4ghz Intel Core 2 Duo 250gb upgraded to 8gb

Thanks for the advance I rang apple and they are sending me replacement disks, if that doesn't work I'll have to go to my nearest apple store which isn't so near...
Just one more question!
I just read your 'step by step to fix your mac' and came across the section on 'What you will need if on 10.6'
I was planning on buying my own copy of OS X Snow Leopard 10.6 as a borrowed one to do the reinstall. Would I still be able to get machine specific 10.6 for my machine or would I have to get the retail version?
Cheers for the replies your short to the point answers have been very helpful

If you reinstalled any third party applications after doing the erase and install, these might be causing the KPs. A reinstall in that case won't prove it isn't software related.
If you don't have the Snow Leopard Install DVD, how did you reinstall? You reinstalled 10.8?
Is there more to the panic log than that? If so, can you post the full log.
You appear to be running 10.8, why then do you want to install Snow Leopard?
What replacement discs is Apple sending? As replacements, they would be sending the grey machine specific discs that originally came with the computer.

No I haven't reinstalled anything after doing the erase and reinstall accept the software updates from apple.
As I said before I borrowed a OS X Snow Leopard 10.6.3 to erase the hard drive and reinstall the system, I just wanted some advance on purchasing my own because I was just going to purchase the retail version from the online store.
The full log is there at the top in my first post there is no more to it.
I am running OS X Snow Leopard 10.6.8 which was originally 10.6.3 before updates.
And yes, apple is sending me the grey machine specific discs that would have come with the MacBook when it was bought new 4/5 years ago.

Might try reseating the RAM. RAM is a likely culprit with KPs. You can trust a positive, but the Hardware Test isn't a very reliable diagnostic for negatives. You could run it a few times in extended.

Ok thanks, will give that a go in the mean time. The discs are being sent free of charge, so they'll just be an added bonus from all this - it's always bothered me that I didn't have them.
Also, it might be a stupid question, but what do you mean by 'you can trust a positive but the hardware test isn't reliable... etc'?

Just that the Hardware Test isn't really great at finding errors, which is to say it isn't great at diagnosing. So if it comes back empty handed (a negative), that doesn't mean nothing is wrong. But if it reports an error (a positive) it can be trusted.
If you can boot the computer and get on the Internet to download memtest, it would run a better check on the RAM than the AHT. But even there, as RAM errors are known to be elusive and random, it might take a fair number of loops to find anything.
So, in case you can:
To test the memory, get memtest and run it in single user mode, where it will test as much memory as possible, more than with the OS loaded.
You can get memtest + directions from the link below. However, ignore running it from Terminal. Instead, boot into SU Mode, CMD-S at the startup chime. (Best to startup from a full shutdown.)
At the prompt, simply type /usr/bin/memtest all 3 -L (From this link It will be installed in /usr/bin/) Then hit return. This will run three loops of memtest and create a log in Console in Utilties. The log may also appear in the Hard Drive Folder (Macintosh HD, unless you have renamed it), which is either on your Desktop or in the sidebar of a Finder window.
If you want to run memtest longer, which may be advisable, since RAM errors can be very elusive, you can change the number of loops it runs by changing the number. For example, to run 8 loops you would enter /usr/bin/memtest all 8 -L.
If you want to quit the test at any time, just hit control-c
When finished, you can just type in "reboot" and hit return.
Direct link for the download.
Here is an Apple article that shows how to get at the RAM on a MacBook

I've tried reseating the RAM with no luck
I downloaded the memtest and tried to boot in SU mode to run it. It starts up in the mode then a similar kernel panic (there's a few extra lines to it) pops up in the SU mode - black screen white text - without the restart prompt.
I'm doing the check now by running it through the terminal, so far it hasn't come up with anything but the requested, avaliable and allocated memory is 2069mb when there is 8gb installed might this mean that the other 6gb is causing the kernel panic?

It's not that the other 6GB is responsible for the KPs--and I'm kind of confused about this myself, and will have to do some more research as to how to get memtest to test all the RAM. (I believe memtest was developed before RAM capacities became so large.)
On all other systems, memtest executes in 32-bit mode with a maximum testable limit of 2 GB.
It might be that it tests incrementally more of the RAM on subsequent passes. But don't really know. I will have to look into this.
It does sound like you need to bring the MB in for a proper, professional diagnosis.
