Interpreting crash logs isn't easy, and you haven't given us any information to help troubleshoot your problem.

I assume you're running OS X 10.4.2 by the fact that you've got Darwin kernel version 8.2.0.

What is the exact configuration of the Cube? When does the crash occur? Is this a one time thing, or does it crash like this a lot? What programs are you running when the crash occurs? There's mention of USB drivers in the log -- are you using any USB devices, specifically, some kind of USB hub?

I would help if, instead of posting a crash log, you explained the situation surrounding the crash in detail. This would better help us help you.
 
Hello, the exact configuration of my cube is,

Giga 7557 1.5GHz Upgrade card, 1.25gb Memory, 80gb samsung hard disk, Apple GeForce3 64mb Card with a 15"ADC Flat Panel Monitor.
I have a LG External DVD-RW on Firewire and the orginal HDD out of my cube on the other Firewire bus. On USB there is the keyboard and mouse and a Creative 24bit Soundblaster External Card.
I had a BT Voyager 105 USB ADSL Modem, but after finding lots of links that the USB drivers cause all sorts of funny problems with mac's I have Purchased a NetGear ADSL over Ethernet Router. It has only crashed once since then. There doesn't seem to be any reason for it crashing, there is no pattern. It stayed up and running for 66 hours, the other week, then proceeded to crash three times when I was browsing the internet and checking my mail. I have tried using safari, IE, Netscape, FireFox and Opera. But that doesn't seem to make any difference. The only common thing is that in the panic.log, it always comes up with the same crash exception. The only difference being, sometimes it comes up with a grey screen telling me I will need to restart my mac by holding down the power key for 4-5 seconds and other times it just freezes, the mouse won't work, the clock stops, the caps lock light doesn't come on when you press the button. the only thing I can do is hold down the power button until it turns itself off.

Thats about all I can tell you I think, hope this helps.
 
The only thing I would try is to run the computer without any external devices attached (USB or FireWire) and see if the situation improves. USB devices are known to cause a lot of problems, and I'd suspect the Sound Blaster first and foremost.

If running without any external devices doesn't help, I would next suspect the processor upgrade or a RAM stick, but it could also be software-related.
 
I have tried changing the ram stick over (I even bought a new one to double check) I don't think it is the soundblaster, as it has been running fine for ages with it plugged in, but I will try. I have read in some of the forums that a worn mouse can do something similar to this. I have replaced the orginal key board because some keys didn't work on it any more, but I have the orginal black mouse. Do you think it could be that? It doesn't seem to crash when it is left alone, only when I am using it.
