iMac Retina in Kernel Panic

I have an only 4 month old late 2014 iMac Retina 5k that has restarted itself 4 times this morning due to kernel panic. I'm wondering if anyone can help me diagnose the error report. I just upgraded to Yosemite 10.10.4 yesterday, which I only think is interesting because this never happened before then. I have AppleCare, so I will take it to the genius bar ASAP if need be, but I'm wondering if I should start by rolling back the update. Here is my error report:

Apple has not provided an easy way to recover from this condition. If you don't feel able to carry out these instructions, get someone more experienced to help you. One option is to make a "Genius" appointment at an Apple Store. It's a free service, and anyway you're under warranty.

You need at least two complete, independent backups of all data before proceeding. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

Start up in Internet Recovery mode by holding down the key combination command-option-R at the startup chime. Release the keys when you see a spinning globe.

Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

In the OS X Utilities screen, select

Utilities ▹ Terminal

from the menu bar at the top of the screen—not from any of the items in the OS X Utilities window.

Follow the procedure in this thread to split up the Fusion Drive. The long string of letters, numbers, and dashes that you will have to enter will be different in your case. Copy and paste it from the Terminal window into the command.

This operation will remove all data from the Fusion Drive, so you had better be sure of your backups.

Quit Terminal, then repair the Fusion Drive (see under "Troubleshooting" on the linked page.)

Quit Disk Utility. You should then be able to restore the data from a backup in the main screen.

Hi Linc,

Thanks very much for your reply. When I perform the disckutil in Terminal, is the "long string of letters, numbers, and dashes" the Logical Volume Group ID? Here is the info from my diskutil:

CoreStorage logical volume groups (1 found)

So I would use 505F3B49-576B-4F52-A78A-B063D0693BE4?

Thanks again.

Hi Linc,

I just wanted to say thank you again for your help (you were much more helpful than Apple phone support). I was finally able to set about your repairs yesterday, and my computer hasn't crashed yet today, so fingers crossed it remains stable.

Just for your own reference for the future, the sudo command didn't work in the terminal on a fusion drive. I found myself having to use this command instead:

diskutil coreStorage delete lvgUUID

Where the lvgUUID was the long string of letters and numbers that you told me to look at. When I tried the sudo command initially, it said command not found. I wanted to share that in case someone else is trying the same thing on a fusion drive.
