Re: kern/58335 (Kernel panic when shutting down a virtual machine with Virtio devices)

I can't reproduce the problem anymore with kern.detachall=0. But with
kern.detach=1 I get a different panic.
This is what I get with with kern.detachall=0.

Synopsis: Kernel panic when shutting down a virtual machine with Virtio devices

State-Changed-Why:
Thanks for the report! Can you see if you can still reproduce the
symptom? And, can you also try reproducing the symptom after running
`sysctl -w kern.detachall=1' (each time you boot)?
You can find daily kernel builds for testing here:
