That's really unfortunate to hear. If I was in your shoes - If not
solved by the end of the return period I would return the machine and
purchase one from a vendor that has been testing, fixing BIOS issues and
supporting Linux.

I'm not going to pick favorites, but Dell, Framework, HP, and Lenovo all
have offerings that they do this.

By chance does the BIOS offer access to "AMD PBS" or "AMD CBS" menus?
If so, there may be an option nestled in there for dGPU D3 behavior.

I got it working. My kernel, which I build up from defconfig, was
missing CONFIG_HOTPLUG_PCI_PCIE. It makes sense, but I wish there was
more evidence that pointed me to this option. At least we can close the
loop here in case anyone else runs into this problem. As a side benefit,
enabling this option also got the dGPU to enter D3cold where before the
lowest it would get is D3hot.

Thanks again,

That's great news! I'll add a check to flag this in amd-debug-tools too to help anyone else in the future.

Thanks,
