New Kernel Panic on Yosemite
Solution 1:
My thought: The computer went to sleep and was unable to Wake for Network Access causing a kernel panic related to the the IONetworking drivers.
Potential solutions: Delete the sleepimage file found in the
/var/vm/
Folder
Delete the contents within
/Library/Preferences/SystemConfiguration/
This will delete the wifi network information from the computer. For example, the password to you home network.
Restart your computer after removing these files. Go to System Preferences > Sharing, add your preferred Sharing name I.e. Xxx's iMac
I believe this will take care of your issue.
