    yes thats a kernel panic. if it happens regularly then something is wrong with your setup. (firstly disconnect all unnecessary usb devices, and try a basic config for a while, if that doesn't help, it might be a software issue.)

    i've had about one KP in a year on my macbook. you shouldn't see this very often!

    Here is the info on Kernel Panics from Apple:


    And how to help troubleshoot them:


    As vandozza said, kernel panics should be extremely rare, if they happen at all. Of the three Macs I've owned since 2007, and the half dozen or so at work I also use from time to time, I've only had one kernel panic, and that was because I mistakenly unplugged a USB hub with devices plugged in, in the middle of a file copy.
