@eskimo, Is this the kind of information you're looking for? Feedback ID sent in February: FB8989607

Welp, This was requested to be moved to this forum (from the discussions.apple.com forum) due to the 'beta' issues. Kernel panics continue today on the release version of 11.3. ProductName: macOS ProductVersion: 11.3 BuildVersion: 20E232 I'll ignore this thread, and reopen the issue with Apple Support.
