Recently I have noticed my MacBook Pro restarting as soon as it tries going to sleep. If I plug it in and leave it on for the whole day, it will work fine.

  1. I have tried resetting SMC, NVRAM etc.

  2. Apple Hardware diagnostics says there is no issue with the machine.

  3. First Aid says disk is okay.

I have also tried going into Recovery and deleting the sleepimage. Now have hibernate mode disabled. Still facing kernel panic.

This is what I am getting in the log.

  • Did either of you try a new OS load? Do you have any 3rd party drivers (printers etc...) that might be causing problems?? I would try it with a new OS load from the internet recovery and a wiped disk with no 3rd party apps installed and see if that works. If so its a software issue of not then its a hardware issue.

  • Can you provide the output of the following command pmset -g log when this issue happens?

  • This clearly is a PCI device error.

Do you happen to have the GPU problem stated here? If you do please do take care of Part 2: improve thermal and power management.
