I have run across a reoccurring Kernal Panic. Thoughts?

Question

I am thinking it is a Ram issue, component of some type, but before returning to the Genius Bar, thought it might be a good idea to ask if anything in the log is familiar?panic(cpu 0 caller 0xffffff8016785f6f): Kernel trap at 0xffffff7f99056f90, type 14&#x3D;page fault, registers:  CR0: 0x000000008001003b, CR2: 0xffffa48048a0a030, CR3: 0x000000002915f000, CR4: 0x00000000003627e0  RAX: 0xffffff820e28b9b0, RBX: 0xffffff820e28b9c4, RCX: 0xffffa48048a0a000, RDX: 0x0000000000000200  RSP: 0xffffff820e28b9b0, RBP: 0xffffff820e28b9d0, RSI: 0xffffff804a621800, RDI: 0xffffff804910f000  R8:  0x000000004484a179, R9:  0x0000000000000000, R10: 0x0000000000000000, R11: 0x0000000000000009  R12: 0xffffff804a621800, R13: 0xffffff8048988be0, R14: 0xffffff804a621800, R15: 0xffffff804910f000  RFL: 0x0000000000010282, RIP: 0xffffff7f99056f90, CS:  0x0000000000000008, SS:  0x0000000000000010  Fault CR2: 0xffffa48048a0a030, Error code: 0x0000000000000000, Fault CPU: 0x0, PL: 0, VF: 1

Your Mac appears to be a 15-in 2017 model with soldered RAM and soldered drive.Apple Panic reports have severe useful bits of information in them.In this report, the panic reason is a Page fault, a reference to memory not owned by the process trying to access it.The kernel extensions at the "scene of the crime" are always important, because they give background around or near where the problem is occurring. Yours was Airport and related drivers.The BSD process that incurred the fault can also be illuminating. This one was Kernel-task.The loaded kernel extensions should be inspected. Non-Apple extensions are listed first. The good news is that you are not showing any third-party extensions. The bad news is that the MacOS kernel has been tested so long and hard, it does not spontaneously produce panics like the one you posted._______Your mission now is to find additional older kernel panics and take a look at these key items in the older reports. What you are trying to determine is whether there is a Trend.case a) Kernel panics for the same panic-reason, with the same extensions present, in the same BSD process, are likely to be a Trend.A Trend can indicate a Hardware problem in a specific area, or possibly clobbered software. A Re-Install in place should be a part of the debugging process. By design, this does not bulk-erase anything except System Directories, so all your files and added Applications are intended to be preserved.case b) Kernel panics for different panic reasons, with different extensions present, in different BSD processes, "all over the Map" are a distinct NON-Trend, and they mean something different.NON-Trend often correlates with RAM memory problems. This is because MacOS slightly randomizes the load point of key routines as a hedge against fixed-address attacks. If you have a weak memory cell, each Restart will move that cell into a different routine, and cause it to wreak a different kind of havoc each time.

Please post the ENTIRE kernel panic report, not just this tiny fragment.Please do not post any Hang reports or Application panics. If you must, only the first 20 lines of those are one any way useful in this situation.

Sorry Grant, Way too used to the first 2-3 lines of a Blue Screen containing enough to start troubleshooting.  The Page Fault lured me into thinking it might all be contained in the first part.  My bad.  Here is the entire log dump.

Great walk-through.  I will grab the QA person that is using this Mac and see if he has additional logs.  We had received it back from the Genius bar without any explanation other than it seems ok and the disk was wiped.  So the QA person restored the system with his own time-machine done before the Genius bar and then the panic&#x27;s started again.I&#x27;ll go grab more logs and look for trending or non-trending in my comparisons.Thanks!

I have run across a reoccurring Kernal Panic. Thoughts?
