lima causes kernel panic on macos 15.4 beta 1

[ideesnoires]

Description

limactl start either with qemu or vz backends leads to a kernel panic. also described here: docker/for-mac#7597
now also part of known issues in the release notes of the beta: https://developer.apple.com/documentation/macos-release-notes/macos-15_4-release-notes#Virtual-Machines
it's not a bug in lima, just putting it here so other users don't have to search so hard. maybe some security people want to look into this, kernel panic triggered from user mode should be interesting.

This issue seems to be specific to M4 CPUs and not affect older CPUs.
