Re: panic in wscons booting current evbarm64 iso under virtualization on Apple Silicon

[John Klos <john%klos.com@localhost>]

Hi,

Quick note: I've been using UTM to run aarch64 VMs for quite a while on an 
M4 MacBook Air. Today I updated from UTM version 4.75 to 5.08, and got a 
panic with VMs that worked just fine with 4.75.

Although your panic and mine are different, perhaps try an older version 
as a data point?

John
