AGESA & multiple GPUs

Hello, in his most recent video on Level1Linux channel, Wendell mentioned that there were several new bugs present in the AGESA version, some of them related to running multiple GPUs: However, I haven’t been able to find any more information about these bugs.

I’m thinking about updating my X370 Taichi UEFI to 5.10 version as this is the first X370 Taichi UEFI in the very long time that has been relatively well received by folks at However, this UEFI version incorporates AGESA Pinnacle and inability to run dual GPUs setup would be a deal breaker for me.

FWIW, I’m doing an UEFI update anyway, as this is newly build PC with prehistoric UEFI pre-installed on motherboard. I just have to decided which version I’m going to update to.

So what exactly are the bugs mentioned in Wendell’s video? Are they still present in official AGESA release (as oppose to beta releases)?
