Chosen Solution
Hi, I have my MacBook Pro 2016 that automatically turns off giving error message every time when CPU Proximity reaches 60 degrees C. At that temp fans do not even start. I installed Macs Fan Control app and set it up to start fans at 40 degrees and go max rpm at 50 to be able still to use my laptop, so fans are working. Here is latest kernel panic report I just got. Did anyone experienced something similar? Any ideas if it could be solved somehow? Or it is logic board… Thank you in advance! hu Jan 10 23:32:12 2019 Panic Report *** panic(cpu 2 caller 0xffffff800aab4494): “Invalid queue element linkage for 0xffffff801f0c7520: next 0xffffff80eba83860 next->prev 0xffffff801f0c7520 prev 0xffffff80233db4f0 prev->next 0xffffff801f0c5520”@/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-4570.71.17/osfmk/kern/queue.h:245 Backtrace (CPU 2), Frame : Return Address 0xffffff913db8bb10 : 0xffffff800aa6e1c6 0xffffff913db8bb60 : 0xffffff800ab96aa4 0xffffff913db8bba0 : 0xffffff800ab88d74 0xffffff913db8bc10 : 0xffffff800aa201e0 0xffffff913db8bc30 : 0xffffff800aa6dc3c 0xffffff913db8bd60 : 0xffffff800aa6d9fc 0xffffff913db8bdc0 : 0xffffff800aab4494 0xffffff913db8be20 : 0xffffff800aab70b9 0xffffff913db8be60 : 0xffffff800aa8aa8d 0xffffff913db8be90 : 0xffffff7f8c15b3a3 0xffffff913db8bf30 : 0xffffff7f8c15be64 0xffffff913db8bfa0 : 0xffffff800aa1f557 Kernel Extensions in backtrace: com.apple.kec.pthread(1.0)[E64F7A49-CBF0-3251-9F02-3655E3B3DD31]@0xffffff7f8c158000->0xffffff7f8c166fff BSD process name corresponding to current thread: cfprefsd Mac OS version: 17G4015 Kernel version: Darwin Kernel Version 17.7.0: Fri Nov 2 20:43:16 PDT 2018; root:xnu-4570.71.17~1/RELEASE_X86_64 Kernel UUID: F39BC8AD-8981-3617-BF39-E68CAA3268D5 Kernel slide: 0x000000000a800000 Kernel text base: 0xffffff800aa00000 __HIB text base: 0xffffff800a900000 System model name: MacBookPro13,1 (Mac-473D31EABEB93F9B) System uptime in nanoseconds: 27691351834 last loaded kext at 12066357159: com.apple.driver.AppleGraphicsDevicePolicy 3.20.14 (addr 0xffffff7f90237000, size 77824)
Ouch! While your is system running hot, thats not your problem! The Panic report is a bad RAM address return. The first thing I would do is trim away as much as you can from your drive. Depending on its size you should have at least 1/4 of the drive empty! Modern OS’s leverage virtual RAM, cache & paging so when your drive is very full you can encounter this exact issue. What is happening is the drive is too full so the OS can’t find the needed space to work.
