I have experienced 5 kernel panics over the last few months. Using a mid-2012 MacBook Pro running Yosemite 10.10.4.
I have reinstalled Yosemite and have erased, repartitioned and reinstalled. I have been on the phone to AppleCare and have had a Genius run diagnostic tests, nothing found. No one has yet looked at the logs.
The only thing I can find in the logs that is common to every kernel panic is that the last loaded and/or unloaded kext in every case has been:
com.apple.driver.AppleUSBCDC 4.2.2b5
or
com.apple.driver.AppleUSBCDC 4.3.3b1
Does anyone have any ideas as to what the problem might be?
Thanks for reading.

Let me guess: the kernel panics appeared with the 10.10.3 update? Well, then I am 98% certain it is a bug in OS X Yosemite. Welcome aboard. The kernel panics are totally erratic, some users have also graphics glitches. The only common feature is having a Intel HD 4000 GPU.
On MacBook Pros with dual GPU you can avoid the problem by disabling Automatic Graphics Switching (System Preferences > Energy Saver).
After countless phone calls with Apple, I will take my Mac to the Apple Store tomorrow. I am sure they won't find a thing. Then they will keep my Mac for five days, replace the logic board and the issue will persist. Please proof me wrong Apple...
Please contribute to the thread in the apple discussion forum and file a bug report (with link to the thread).
