M1 Max MacBook Pro(16') Frequent crash and reboot

This problem occurs on two identically configured MacBook Pros in a row, usually when the computer crashes, dies, and reboots shortly after opening the lid and starting to use it.
And you get an almost identical panic log:

panic(cpu 1 caller 0xfffffe0023b2a688): busy timeout[0], (60s): ‘IOUserEthernetController’, ‘IOUserEthernetController’ @IOService.cpp:5521…

It happens two to three times a day when it is severe. I hope you can help me, thank you very much.

A similar question was found for your reference at:


Most questionable software.

  • parallels Desktop
  • surge

Care to share more information about your setup and the hardware attached to the computer?

have you tried just using wireless or a different ethernet adapter?

One of the error messages reported was as follows:

M1 Max 10 core CUP, 24 core GPU, 32 Memory.

Are you connecting it to any devices like docks or something?

No link to docks and crashes when not connected to power

Ok! That’s odd, so you are saying both computers have the same issue? Then it’s a software issue most probably. Did you try to clean install one of them?

Your conclusion should be correct, it is a software problem, I currently suspect that the software “parallels Desktop” is causing the “network I/O” problem, I have uninstalled this software for more than a day now and no crash has occurred yet, I am still watching

I have parallels installed since day one and no issues at all with crashes.

Thanks for the reply, are you also using parallels on the M1 Max chip? And is it running all the time?

M1 Max, 32 Core GPU, 32GB RAM.
Parallels 17.1.1 running Windows 11 and is pretty much all the time as that’s where I need to test some development work.

Thanks, I need to keep watching (have uninstalled parallels for now)
