    I have experienced a number of kernel panics on my 2.5 months old 15'' core i5 MBP, roughly one every 1-2 weeks. It seems to occur completely randomly, i.e. the machine has not been under particularly heavy load or running any non-standard applications at the time of the kernel panics. In Console, the "Kernel Extensions in backtrace" tends to say something about "", so maybe it is a graphics issue? I do not think this is normal for a new machine, and I'm planning to contact Apple because of this. Do you think Apple will replace my machine if I will demand that, within the 1 year warranty?

    It's highly unlikely they will replace your machine because it sounds like a software problem. From what you write, it sounds like a graphics card driver is causing the problem. 10.6.5 (or the Snow Leopard Graphics Update) is hopefully going to include some better graphics card drivers that will hopefully fix a lot of these types of problems.

    You could try switching off the auto graphics card switching and just use the NVIDIA card which may stop the problem until better drivers are released for the integrated graphics card.

    Could be bad ram memory, talk to apple and see if they can replace the ram for you.

    This happened to mine.

    They had me re install the OS and that didn't fix it then they had me run the Apple hardware test and that brought back no problems but it still kept happening and because I was within the 14 days they replaced the machine.

    I had the same problem about six months ago and RAM was the issue.

    One out of three restarts would give me a loud buzz from just below left speaker.

    If you bought third party RAM, replace it with the original that Apple shipped with the machine.

    Error message in trace sounds like something crashing in graphics switching. You could try calling support and see what they say. Tier one Apple Support is actually pretty decent. A few of our techs came from Apples Support call department and they actually are really talented guys. Worst case, you reinstall and that doesn't help, and the machine either gets swapped out or repaired. A win for you either way.

    Thank you all for your replies. I'm not using any third party hardware (for instance, I have not updated the RAM). In case someone has an idea how to interpret the log message, here is the whole thing, from the last panic:
