Hey everyone. My first post. I'm having the following issues with my Mac Pro. I'm hoping you might have suggestions and can help me interpret my Kernel Panic (below). Specs: 2008 2.8Ghz Mac Pro 8-Core Leopard 10.5.8 2GB Apple RAM, 8GB Crucial RAM Apple 320GB Hard Drive 3 additional Seagate internal Hard Drives Airport Card Peripherals: Mbox, SSL Duende, Wacom Graphire Tablet, Apple Keyboard Warranty: 6 months left on Apple hardware warranty Problems: 50% of the time won't wake up from sleep Starts up but sends no signal to displays Regular Kernel panic on startup Kernel panics during use CD drive is noisy (when not in use) occasionally Troubleshooting I have taken the following steps to fix it (both at the apple store, with phone support and on my own). Reset PRAM Reset SMC Apple Extended Hardware test - showed nothing Reinstalled Leopard Removed all 3rd party software Removed all 3rd party hardware (including RAM, Hard Drives, Tablet, etc.) Repaired Disk Permissions Rebuilt internal drive with disk warrior Dragged my 45 pound computer to the Genius Bar I have been getting Kernel panics on and off for months. But I have had about 20 in October. Is this unacceptable? Should I insist on a replacement computer? I'm not really comfortable with them swapping hardware if they dont' know what's going on. I'll post my most recent Kernel panic in the next post.
