Anyone else seeing frequent crashes/reboots with the following error?

"busy timeout[0], (60s): 'IOUserEthernetController', 'IOUserEthernetController'"

That's worrying, since it isn't tied to a specific program.

If you're still within the no questions asked return window, I'd send it right back. This is a premium computer, and such an issue warrants disposing of it immediately if you can. Turn your problem into their problem, and avoid losing a cent.

Otherwise I'd try a reinstall.

Yes I get that pretty frequently, usually after docking and opening the lid. I think it related to parallels, it seemed to happen less often after I closed my windows 11 vm. I also have wireguard, littlesnitch and rancher desktop and they touch the network stack.

I'm also having this issue on an M1 Pro MBP, MacOS 12.3.1, Parallels Version 17.1.2 (51548). I'm actually running a MacOS VM, since I only need it for VPN/network isolation and don't want to pay for a Windows license.

I've noticed I only get the IOUserEthernetController kernel panic shortly after my host machine wakes from sleep. One work around I've found to reduce the frequency of the kernel panics, is to leave my laptop plugged into power as much as possible, and setting the "Prevent your Mac from automatically sleeping when the display is off" option in the Battery -> Power Adapter settings.
