M1 Panic: acc_cifl2c_cmd_ncwr

Hello,

M1 MacBook Pro 13" 16GB constantly reboots with the same panic error: acc_cifl2c_cmd_ncwr

I've spent some time figuring out who is causing this problem.

It happens only if M1 MacBook Pro connects to wired ethernet only (via thunderbolt obviously) with disabled Wi-Fi.

So:

1. Wi-Fi only = no issues
2. Wired ethernet with disabled Wi-Fi = Panic: acc_cifl2c_cmd_ncwr

Tried:

1. Multiple/different thunderbolt hubs = panic
2. Multiple/different thunderbolt cables = panic
3. The latest macOS installed from the scratch = panic
4. Safe Mode = panic

I tried to contact AppleCare support but they wasted my 4 hours with no results.

The issue has been present since day one we got the M1 processor...

The only solution is to use Wi-Fi only which is a shame for PRO users.

Shame on all sides, Apple.
