Ubuntu Jammy VMs freezing on an Apple M1 Pro specifically MacBookPro18,1

Description

Over the past 3 or so months I am seeing increasing freezes in my Ubuntu Jammu JellyFish VMs.

I'm install lima via brew and keeping it updated.

Opening a new shell in instance just stalls.

Is there anything I can do to reduce or collect logging or ascertain the root cause.

I typically have to kill the underlying qemu process to recover from and restart the VM.

I'm going to try 1 CPU versus the default.

The logs are located in ~/.lima/<vmName>/. Please attach them

Thank you, will do the next time a crash happens... It has been stable since I reconfigured to one cpu, but I am wondering if it was when I was using the VM to run a multi-architecture docker buildx builder that was causing the problem... OS X running qemu running ubuntu running docker running a builder container running qemu to build a container... Inception.

I wonder if this is related to #1957?

Since I took a newer-than-0.18 version of Lima (with brew install lima --HEAD), and updated to the latest kernel, my AlmaLinux9 VM has been rock solid.
