Recurring Kernel Panics on Retina Macbook Pro

Question

I&#x27;ve got a Retina Macbook Pro which has spontaneous kernel panics. I&#x27;m not sure how to go about troubleshooting it and would love some guidance here. I think experience with reading the logs and understanding what kernel extensions are doing and stuff is what I need, but I don&#x27;t have that experience yet 😟Anyways, some of the KPs happen with a Thunderbolt display connected, some without. From what I can gather from the kext in the backtrace, the Thunderbolt&#x27;s ethernet adapter extension was implicated somehow, leading me to believe the issue has something to do with the Thunderbolt display... But not sure what it really means that it is in that backtrace...Also, the thunderbolt display sometimes flickers off and on. This is not reproducible, it only happens sometimes.

interpretting OS X kernel panics and the kext backtraces but most guides say something along the lines of "check some hardware stuff, if not that, the easiest option is reinstall OS X". That&#x27;s fine and dandy, and I&#x27;m pretty sure it would resolve this issue, but I would really like to understand what the problem is an try to fix it. I can easily reinstall OS X but that&#x27;s no fun and doesn&#x27;t teach me anything. If that&#x27;s what I need to do, I will definitely do it.Thanks for any guidance!

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:A stale or corrupt kernel cacheA damaged OS X installationA fault in a peripheral device, if anyCorrupt non-volatile memory (NVRAM)An internal hardware fault (including incompatible memory)An obscure bug in OS XYou may already have ruled out some of these.    Rule out #1 by booting in safe mode and then rebooting as usual. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.    You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation (after erasing the startup volume) may solve a problem that isn&#x27;t solved by reinstalling in place, without erasing.Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.If your model has user-replaceable memory, and you&#x27;ve upgraded the memory modules, reinstall the original memory and see whether there&#x27;s any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications for your model. Memory that is either slower or faster than specified may be incompatible.The Apple Hardware Test or Apple Diagnostics, though generally unreliable, will sometimes detect a fault. A negative test can&#x27;t be depended on. Run the extended version of the test.In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve booting from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.   Connecting more than one display is another reported trigger for OS X bugs.   If your system is not fully up to date, running Software Update might get you a bug fix.In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.If none of the above applies, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn&#x27;t much point in doing this unless you can reproduce the panic, or if you can&#x27;t, it happens often enough that it&#x27;s likely to be repeated at the store. Otherwise you may be told that nothing is wrong.Print the first page of the panic report and bring it with you.Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you know how to restore, and you have at least  two independent backups.) Don’t erase the recovery partition, if present.Keeping your confidential data secure during hardware repair*An SSD doesn&#x27;t need to be zeroed.

Hi - I have had multiple Kernel Panics in the last week or so... I only seems to happen when I have 2 Thunderbolt Displays plugged in.Does this appear to be a Hadware or Software issue... can you tell?Thank ou in advance for your recommendation.Here is my last from just a little wile ago:Anonymous UUID:       DBCD9269-F529-4297-1062-C8671AA1D211Thu Jan 23 11:00:32 2014panic(cpu 2 caller 0xffffff80274dc19e): Kernel trap at 0xffffff7fa7ac4aed, type 14&#x3D;page
