--- Comment #7 from Robert Crowston <crowston@protonmail.com> ---
> 1. Which GPU are you using?
A gigabyte Radeon RX 6650 XT (I also had success with a much older AMD card).
> 2. Are you using using upstream bhyve and edk2?
Not sure what you mean by 'upstream bhyve' -- I use the bhyve in 13.1-stable
(and have tested -CURRENT too). For edk2, I use the bootroom binary that you
created (https://reviews.freebsd.org/F31899352), but it makes no observable
difference to me to the one from packages -- the GOP driver does not start
(with either GPU).
