Do you have any external devices attached to the iMac? If so, disconnect all external devise except keyboard and mouse. See if you experience any Kernel Panic then. Kernel panics are usually caused by a hardware problem or software as Daniel has mentioned. Frequently RAM, a USB device or a Firewire device can cause Kernel Panic. Do you have an Apple Hardware Test disc? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. 'Looping On' should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure. In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run, perhaps overnight. In case no problem is found after running the test overnight, you can exit the loop and stop the test by clicking on the Stop Test or Cancel buttons.
