Kernel Panic Apple Macbook Pro M1 2016

It seems to be a hardware failure with the SSD.

ANS2 Recoverable Panic - assert failed: [14510]:apcie0[1]: Unexpected link down

ANS2 == Apple NAND Storage version 2 which is referring to the SSD.

Unexpected link down --- sounds like the SSD's link to the system bus & CPU is down.

This is one of the most common ways SSDs fail. In fact most SSD failures will show up when waking the computer from sleep or when powering on the computer.

Kernel Panics and these intermittent SSD failures are also very hard to troubleshoot & confirm, especially when Apple does not train their techs to even read a Kernel Panic. There are only two ways to get Apple to actually repair a device. One is when the Apple Diagnostics or Apple service diagnostics actually report a hardware failure. Second, is when you experience the failure while booted to a clean install of macOS which has not been restored from a backup, and has not had any third party apps installed, nor any external devices connected.

If you have any external devices connected, then disconnect them. If you have any external Thunderbolt SSDs connected, then there is a slim chance this error could be due to the external SSD. These new style Kernel Panic logs are a bit confusing since there is very little information about them and these M-series Macs.

Maybe if you can get a higher level tech engineer at Apple to examine the Kernel Panic log you will be able to have them authorize a repair. Those are your options at this time unless you show the issue exists with a clean install. I doubt the Apple Diagnostics will ever show a problem.

Now, the service team supports that I need to change my motherboard.

I missed this part from your original post since the attempt at paragraphs still left them without any empty lines between paragraphs which made it hard to read.

I concur with the service team that the Logic Board needs to be replaced.
