Kernel panic report diagnosis

Hi, I have had ongoing issues that cause kernel panics to occur often. I have had my computer checked by Apple, OS X reinstalled multiple times but the problem persists. Apple thinks it is a software issue but they have not been able to solve the problem. I got my MBP back from Apple today and once again, a kernel panic has occurred.


This time, the kernel panic occurred when opening a new tab in google chrome. The screen froze and was unresponsive for ~15 seconds before going black. The black kernel panic screen was then shown and I pressed a key to restart it.


Google chrome info: Version 52.0.2743.116 (64-bit)


Here is my macbook pro hardware details:

the actual problem detected in that report is almost impossible to happen naturally. so you should take its guess of memory corruption seriously.

*** Panic Report ***

panic(cpu 2 caller 0xffffff80077b4260): "Possible memory corruption:


You do not have any known "bad actors" loaded, although chrome is known to have memory leaks, memory corruption is generally not a problem. Sometimes memory corruption can be caused by "crazy" USB devices, that write random trash into random parts of memory, so you should disconnect any external USB drives while debugging.


The Apple Hardware test can be put into loop mode to run all night by pressing command-L before initiating the test. It should indicate "loop mode" on the screen when you do this.


This MacBook has soldered-in memory.
