--- Comment #72 from Jamie Landeg-Jones <jamie@catflap.org> ---
I recently tried to install 13.0-RELEASE and 13.0-STABLE (20210701) on a kvm
host, and it hangs the same way described above with q35, but works with
i440-fx

I don't have access to the host (I'm a VM customer)=20

I can get a prompt from the q35 instance by setting in the loader via the b=
oot
menu:

set hw.ata.ata_dma=3D0
set hw.ata.atapi_dma=3D0

However, things are weird (The "Install" menu button doesn't do anything, b=
ut
"Shell" does)

And "reboot" completely hangs after saying all disks synced.

I've attached kenv output. Anything else that would help?

Cheers, Jamie
