    Hey, I had my first kernel panic today!! I am acutally somewhat excited in an unhappy way. It only took 15 months for it to happen.

    Well, anyways, I was wondering if you guys could help find the cause:

    Which applications were running?

    Have you (recently) installed any additional hardware, like RAM, hard drive or even 3rd party keyboard and mouse?

    A good way to check what caused your kernel panic is simply to look at the computer's log.

    Just go under "System Profiler" and on the left side, under the "Software" voice, you'll see "Logs".

    it should be under the file "system.log". you can look through it and try to find the last time you booted up, because just before it you'll see the last application/driver or whatever running. Usually it's the one that caused the kernel panic.

    Well, I installed this stupid RIO thing to make the player compatible with iTunes. This 128mb MP3 player is like 2 years old and was made for iTunes 2.0. I have iTunes 5.0 and was dumb enough to put this RIO crap on my computer all for my girlfriend who wanted some songs off my computer on her player.

    Anyways, I am pretty sure that the above was the cause. I had iTunes running and was trying to burn a CD. It was really weird. It came out of nowhere.

    I tried to get the RIO stuff off of my computer. I do not think that I succeeded. Thank you though. I was just trying to find the EXACT cause. I had a general idea. :)

    Bad hardware, or bad drivers, are typically the cause of KP's. The backtrace you wrote to us doesn't say anything except for Hex addresses in memory, so we can't diagnose what happened unless we have some form of electronic ESP. If you installed that "RIO" driver, and then experienced the KP's then that is definitely the cause. I bet that the extension was not compatible with the 10.4 kernel.

    Does it mention anything like blah.ext or blah.kext (replacing 'blah' with anything) in the log before what you gave us? That would give a clue as to what is happening.
