Unresolved Kernal Trap OSX 10.4.11...HELP!

The Mac Pro I've been using in the studio keeps having a kernal panic and shutting down to the black screen where I must hold down the power button to restart. I saved the error message upon rebooting and was hoping someone on here could shed some light on what's going on. I'm running OSX 10.4.11 on a fully upgraded Mac Pro with 16 GB of ram.

Here is the message as follows:

panic(cpu 1 caller 0x001A3135): Unresolved kernel trap (CPU 1, Type 14=page fault), registers:

Something to do with this? --> com.motu.driver.USBMidiKext(1.3.4)@0xae9000

Do a web search for that line and it turns up others mentioning Midi device drivers, Mac Intel issues, etc.

Understanding crash logs isn’t easy and it’s hard (sometimes impossible) to decipher the cause of the problem. Take a look at Apple’s Crash Reporter document at http://developer.apple.com/technotes/tn2004/tn2123.html Also look at Tutorial: An introduction to reading Mac OS X crash reports

http://www.macfixit.com/article.php?story=20060309075929717

Kernel panics are usually caused by a hardware problem – frequently RAM, a USB device or a Firewire device. What external devices do you have connected? When trying to troubleshoot problems, disconnect all external devices except your monitor, keyboard and mouse. Do you experience the same problems?

To eliminate RAM being the problem, Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.

Do you have an Apple Hardware Test disc (the AHT is on the Install/Restore DVD that came with your Mac)? 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.

May be a solution on one of these links.
